3G, HSPA and FDD versus TDD Networking, Second Edition is the only book that contrasts the network capacity gains that may be achieved with the advent of adaptive antenna arrays and HSDPA-style adaptive modulation techniques in the context of FDD and TDD CDMA cellular networks.

Near-Capacity Variable-Length Coding examines the topic in the context of digital multimedia broadcast telecommunications. Providing insight into VLC coding's applications, characteristics and performance, the book addresses the latest research in the area.

Following the success of the first edition, this edition is revised in light of new developments in near-capacity turbo-transceivers. Coverage includes Multilevel Coding Theory; MLC Design Using EXIT Analysis; Space Time Sphere Packing Aided MLC/ BICM Design; MLC/ BICM Schemes for Wireless Internet and Near-Capacity Irregular BICM-ID Design.

MIMO-OFDM for LTE, WIFI and WIMAX: Coherent versus Non-Coherent and Cooperative Turbo-Transceivers provides an up-to-date portrayal of wireless transmission based on OFDM techniques augmented with Space-Time Block Codes (STBCs) and Spatial-Division Multiple Access (SDMA).

Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication. This book provides coverage of topics in wireless voice communications.

Covers a range of CDMA and MC-CDMA transmission aspects of systems designed for communicating over fading wireless channels. This book offers an introduction to the subject of CDMA systems designed for employment in various application. It also deals with the topic of genetic algorithm assisted multiuser detection.

Voice and Audio Compression for Wireless Communications, Second Edition details issues in wireless voice communications and treats compression, channel coding and wireless transmission as a joint subject.

"Bridging the gap between the video compression and communication communities, this unique volume provides an all-encompassing treatment of wireless video communications, compression, channel coding, and wireless transmission as a joint subject. WIRELESS VIDEO COMMUNICATIONS begins with relatively simple compression and information theoretical principles, continues through state-of-the-art and future concepts, and concludes with implementation-ready system solutions.This book's deductive presentation and broad scope make it essential for anyone interested in wireless communications. It systematically converts the lessons of Shannon's information theory into design principles applicable to practical wireless systems. It provides in a comprehensive manner "implementation-ready" overall system design and performance studies, giving cognizance to the contradictory design requirements of video quality, bit rate, delay, complexity error resilience, and other related system design aspects.Topics covered include* information theoretical foundations* block-based and convolutional channel coding* very-low-bit-rate video codecs and multimode videophone transceivers* high-resolution video coding using both proprietary and standard schemes* CDMA/OFDM systems, third-generation and beyond adaptive video systems.WIRELESS VIDEO COMMUNICATIONS is a valuable reference for postgraduate researchers, system engineers, industrialists, managers and visual communications practitioners.About the AuthorsLajos Hanzo has enjoyed a prolific 24-year career during which he has held various research and academic positions in Hungary, Germany, and the United Kingdom.

Providing an all-encompassing self-contained treatment of Near-Capacity Multi-Functional MIMO Systems , the book starts by categorizing the family of Multiple-Input Multiple-Output (MIMO) schemes as diversity techniques, multiplexing schemes, multiple access arrangements and beam-forming techniques.

This volume provides the reader with a broad overview of near-instantaneously adaptive transceivers in the context of TDMA, CDMA and OFDM systems.

Motivated by the evolution of the consecutive generations of wireless communication systems, this volume provides an overview of the majority of single- and multi-carrier QAM techniques.

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, optimising the use of available bandwidth.
