    Abstract
    This is a 2-part course. Advanced Protocols for Wireless Ad-hoc Networks will illustrate that in Ad-Hoc networks where there is no underlying fixed infrastructure, tasks such as network self-organization, mobility management, adaptive route detection for unicast and multicast applications, and provisioning of Gateway functionality to interconnect the ad-hoc network to the rest of the Internet space must be handled according to rules that are unique to the ad-hoc nature of the system. Topics related to support of QoS at various network layers will also be discussed with emphasis on layers 2, 3, and 4 of the network. We will investigate the performance of these protocols in terms of their level of scalability to different sizes and traffic loads. Topics of security will also be discussed.

    Abstract
    In the last few years, a series of breakthrough innovations have been made to transform analog-intensive RF circuitry into digitally-intensive implementations. In Texas Instruments, this disruptive technology falls under the umbrella of a Digital RF Processor (DRP^TM) platform and enables to integrate almost all of cellular phone modem electronics into a single IC chip fabricated using nanoscale digital CMOS process. The first such single-chip mobile phone was sampled in December 2004 and is now in a mass- volume production targeting ultra low cost handsets for the Emerging Markets. The ultra low cost handsets typically support a single standard, GSM, and are mostly dual-band with occasional quad-band for world travel compatibility. As the Emerging Markets consumers get more sophisticated, there will be an increase in demand for more sophisticated phones with Third Generation (3G) modem interface, as well as wireless connectivity, such as Bluetooth, Wireless LAN, in addition to mobile digital TV and Global Positioning System (GPS). This presentation will also provide an overview of recent advances in digital RF architectures in more sophisticated wireless standards beyond GSM and EDGE.

    AbstractNeural Networks are information processing systems inspired by the ability of human brain to learn from observations and to generalize by abstraction. It has been used in diverse fields such as pattern recognition, speech processing, control, medical applications and more. In recent years, it has emerged as an attractive vehicle in the RF/microwave CAD community to address the challenges in high-frequency electronic modeling and design. Neural networks can learn and generalize from data allowing model development even when component formulas are unavailable. Neural network models are universal approximators allowing re-use of the same modeling technology for both linear and nonlinear problems and at both device and circuit levels.

    Abstract
    RF power amplifiers have received a great deal of attention and development effort over the last decade, mainly due to the challenging requirements of the wireless communications industry. This effort has not only led to some impressive progress in PA performance, it has also led to some revisions and rethinking in traditional PA theory. This course will highlight how these developments will undoubtedly have an impact on PA design in all application areas including but not restricted to wireless communications.

    Abstract
    China ratified its own mandatory Digital Terrestrial Television Broadcasting (DTTB) Standard with acronym of DTMB in August, 2006, adopting Time-domain synchronous-orthogonal frequency division multiplexing (TDS-OFDM) as the baseline technology. DTMB is designed to cater to the largest DTV market in the world. The standard offers higher spectrum efficiency, better immunization to impulsive noises, and fast synchronization capability. It also supports mobile reception and is suitable for the multi-media services. The whole industry chain consists of many major players, both domestic and international, covering transmitter, demodulator, receiver, network equipment, and testing instruments has been well developed. This presentation will provide a brief review on the key technologies, measurement performance, implementation, intellectual properties and the typical as well as extended application of DTMB, with the focus on current status of deployment and the progress of the oversea promotion.

    Abstract

    This tutorial will review the evolution of wireless communications in China. We begin with a discussion of 3G licenses being issued in China. As a result, three different 3G licenses were granted to the three newly restructured service providers. Though the 3G evolution paths are different for those service providers, all of them have chosen LTE as their future technology; similar to many other major service providers around the world. LTE has two modes: TDD and FDD. China Mobile has picked TDD technology (or TD-LTE) as its future revolution and is aggressively pushing TDD field trials. In addition, Chinese government encourages LTE technologies and is investing heavily on LTE related projects including LTE and IMT-Adv. Finally, HK ASTRI has become one of the global leaders in providing TD-LTE technologies and plans to expand their leadership in TDD to LTE FDD as well.

    Abstract
    In this tutorial, you will learn about LTE air-interface standards and technologies. After completing this tutorial, you should have obtained a high level understanding of LTE, knowing its technical features, key advanced technologies, frame structure and resource grid. Both downlink and uplink transmissions will be addressed. For downlink, we will discuss OFDMA modulation, the physical channels and their general processing, the physical signals and MBSFN. We will also highlight the MIMO technologies in downlink, which includes SIMO, transmit diversity, spatial multiplexing and multiuser MIMO.

    In uplink, we will introduce the key feature of LTE, SC-FDMA, which is a technology that strikes a balance between low peak-to-average-power-ratio and the advantages of OFDMA. We will also cover the physical channels and their processing and physical signals. We will introduce the possible use of uplink multiuser MIMO, which is a a technology transparent to the UEs and achieve significant increase in the system throughput. Finally, cell search and random access are covered.

    Abstract
    This tutorial will discuss the power drain or efficiency of mobile terminals and base-stations to define the issues with current cellular systems operation, particularly in base-station or access point designs. Indications will be given for the total power consumption of (UK) cellular GSM and 3G networks. These issues are set to increase with the move from predominantly speech and text messaging to the roll out of mobile broadband, with its much higher data rate transmission requirements and the urgent requirement for lower cost per delivered bit.

    The second half of the tutorial will review the typical approaches that are now being researched to improve the overall efficiency of base-stations and alleviate the high power drain to achieve “green radio” system design credentials with significantly reduced CO2 emissions.

    This tutorial is set in the context of the Mobile VCE, an industry-UK government funded “green radio” research program conducted in 4 UK Universities in collaboration with 11 international industrial sponsor and program monitoring companies.

    Abstract The IP Multimedia Subsystem (IMS) is considered as the platform of choice for providing a unified session control on top of various access network technologies for realizing flexible multimedia applications. IMS, with its access-agnostic session layer, is also driving the concept of merging the fixed and mobile telecommunication networks with the Internet and the adoption of IP technologies within the telecom domain. IMS represents conceptually a combination of the traditional fixed and mobile networks from the telecom domain with emerging VoIP and Internet applications in order to implement a seamless multimedia service environment. This tutorial will address IMS vision, IMS concepts, procedures, protocols and services, fixed-mobile convergence, standardization activities, and early deployments of IMS networks.

    Abstract
    Orthogonal frequency-division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies.

    CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. Multiplexing is sending multiple signals or streams of information on a carrier at the same time in the form of a single, complex signal and then recovering the separate signals at the receiving end.

    Multi-Carrier (MC) CDMA is a combined technique of Direct Sequence (DS) CDMA (Code Division Multiple Access) and OFDM techniques. It applies spreading sequences in the frequency domain.

    Wireless communications has witnessed a tremendous growth during the past decade and further spectacular enabling technology advances are expected in an effort to render ubiquitous wireless connectivity a reality.

    This series of courses will provide exposure to OFDM, MIMO-OFDM and MC-CDMA. Some working experience on signal processing, OFDM, CDMA, radio-frequency electronics, is assumed. In Part 1 of this series, we will introduce a number of rudimentary OFDM topics.

    After completing this course you should be able to develop an understanding of:

    Abstract
    The delivery of private or secret messages has been an issue of concern regardless of method of transport. Since antiquity, it was risky to send a message with a messenger without compromise. As a result, certain methods were developed to assure unintelligibility of a message if in enemy hands or to indicate to the rightful recipient that the message has been compromised or not. In our modern era, most messages and private data are transported over the communications network, which unfortunately is not immune to eavesdroppers, malicious attackers, impersonators and in general to bad actors who, with sophisticated methods access the network and harvest or destroy electronic data. In recent years, government and private industry worldwide are witnessing with concern an alarming increase in such malicious acts that aim to harvest information, destroy or alter files, or impersonate a source.

    In this tutorial we provide an Introduction and a quick historical perspective on information security. Next, we describe key definitions that are useful in cryptography and information integrity, as well as in Network security. We provide a quick and over simplified mathematical background which is useful to understand the complexity of cryptographic algorithms. For example, what Prime Numbers are, what Modulus arithmetic is and how it works, and what the Greatest Common Divisor is and how it is calculated. The tutorial concludes with the description of popular Symmetric and Asymmetric Ciphers, such as the RSC, DES, AES, RC4, ECC, RSA, D-H, Merkle, and Shamir.

    Abstract
    The delivery of private or secret messages has been an issue of concern regardless of method of transport. Since antiquity, it was risky to send a message with a messenger without compromise. As a result, certain methods were developed to assure unintelligibility of a message if in enemy hands or to indicate to the rightful recipient that the message has been compromised or not. In our modern era, most messages and private data are transported over the communications network, which unfortunately is not immune to eavesdroppers, malicious attackers, impersonators and in general to bad actors who, with sophisticated methods access the network and harvest or destroy electronic data. In recent years, government and private industry worldwide are witnessing with concern an alarming increase in such malicious acts that aim to harvest information, destroy or alter files, or impersonate a source.
    In this tutorial we provide a simplified description of Quantum Cryptography (QC), the qubit, the superposition of states, and the polarization of photons, the quantum key distribution (QKD), the BB84 and B92 protocols, the K05 enhanced protocol, the generation of entangled photons and the teleportation phenomenon, and the vulnerabilities of realistic quantum networks. We continue with Chaotic processes and Chaos Cryptography, and we introduce Chaotic Quantum Cryptography. We describe biometrics in communications as part of security and privacy, and we finish up with security of the next generation optical network in which we introduce and describe methods for intrusion detection, countermeasure strategies and also autonomous network counterattack scenarios.

    Abstract
    In the context of a rich scattering environment, employing multiple antennas at the transmitter and receiver provides a capacity increase that is linear in the minimum of the number of transmit and receive antennas. This seminal result of Foschini & Gans and Teletar has opened the new field of space-time communications. In this tutorial we introduce the key concepts of space-time communications, focusing on transmission in a quasistatic channel for which a good estimate of channel state information is available at the receiver but not the transmitter. Both low-latency (trellis codes) and high-latency (LDPC codes) solutions will be presented.

    Abstract
    This tutorial traces UWB technology through history, regulations, standards, system implementations and commercial applications. Methods of generating and modulating UWB signals are described and set in the context of UWB proposals for IEEE802 Standards. UWB antenna, radiation, and propagation phenomena, including unique behavior in multipath are presented in contrast with narrow band radio. Examples of UWB link margins including data throughput versus range and system data capacity (up to 2 Gb/s) are compared with conventional and much higher power 802.11a/b systems. The future of UWB is a mix of wireless communications, precision positioning and radar. UWB can enable an accurate indoor adjunct to GPS with centimeter accuracy. Discussions of applications show that UWB capabilities make possible delivery of location-specific content and information, tracking of high value assets, security systems and various automotive and interesting home based "location awareness" systems.

    Abstract
    A communication network where an information source communicates with a sink via topologically-imposed distributed and potentially collaborating relaying nodes, is referred to as a Cooperative Communication Network. The aim of this tutorial is to expose an industrial and academic audience to the challenges related to the analysis and design of such recently emerged networks at PHY and MAC layers - with particular emphasis on application within cellular, ad hoc and sensor networks.

    The tutorial is divided into several sections: application scenarios, historical background, hardware design issues, channel models, cooperative and distributed transceiver structures at PHY and MAC layers, and elements of cross-layer design. These topics are essential for understanding the design of these networks.

    The learner is expected to be familiar with the functioning of modern communication systems. Knowledge in channel modeling, STC design and MAC is advantageous but not vital.

    Abstract
    A Wireless Sensor Network (WSN) is made up of a large number of sensors which are extremely small, low-cost, and low-power devices that collect environmental data (acoustics, light, temperature, humidity, imaging, etc.) that is then communicated through radio or optical means to infrastructure processing nodes. WSNs may consist of up to thousands of nodes which can be deployed in very high density settings (e.g., homes, highways, buildings, cities) and infrastructures for monitoring and/or controlling purposes. Applications may range from detecting and monitoring occurrences of natural disasters and homeland security to military surveillance. This introduction to emerging WSN applications reveals how developments in micro- and nanotechnology have aided advancements in WSNs and highlights implementation of several real systems that hint of tomorrow's potential.
