Cover of Near-Capacity Multi-Functional MIMO Systems
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. Sophisticated coherent and low-complexity non-coherent MIMO receivers dispensing with channel estimation are considered in both classic and cooperation-aided scenarios. It is demonstrated that in the presence of correlated shadow-fading, cooperation-assisted systems may be expected to outperform their non-cooperative counterparts. The book contains a 100-page chapter on the unified treatment of all block codes in the context of high-flexibility, cutting-edge irregular Linear Dispersion Codes (LDC), which approach the MIMO-capacity. The majority of the book's solutions are in the optimum sphere-packing frame-work.*
Sophisticated amalgam of five year's near-capacity MIMO research* Detailed examination of wireless landscape, including the fields of channel coding, spacetime coding and turbo detection techniques* Novel tool of Extrinsic Information Transfer Charts (EXIT) used to address recent developments* Material presented logically, allowing advanced readers to turn directly to any specific chapter of interest* One of the only books to cover these subjects, giving equal weighting to each

Cover of Turbo Coding, Turbo Equalisation and Space-Time Coding
Covering the full range of channel codes from the most conventional through to the most advanced, the second edition of Turbo Coding, Turbo Equalisation and Space-Time Coding is a self-contained reference on channel coding for wireless channels. The book commences with a historical perspective on the topic, which leads to two basic component codes, convolutional and block codes. It then moves on to turbo codes which exploit iterative decoding by using algorithms, such as the Maximum-A-Posteriori (MAP), Log-MAP and Soft Output Viterbi Algorithm (SOVA), comparing their performance. It also compares Trellis Coded Modulation (TCM), Turbo Trellis Coded Modulation (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iterative BICM (BICM-ID) under various channel conditions. The horizon of the content is then extended to incorporate topics which have found their way into diverse standard systems. These include space-time block and trellis codes, as well as other Multiple-Input Multiple-Output (MIMO) schemes and near-instantaneously Adaptive Quadrature Amplitude Modulation (AQAM).
The book also elaborates on turbo equalisation by providing a detailed portrayal of recent advances in partial response modulation schemes using diverse channel codes. A radically new aspect for this second edition is the discussion of multi-level coding and sphere-packing schemes, Extrinsic Information Transfer (EXIT) charts, as well as an introduction to the family of Generalized Low Density Parity Check codes. This new edition includes recent advances in near-capacity turbo-transceivers as well as new sections on multi-level coding schemes and of Generalized Low Density Parity Check codes * Comparatively studies diverse channel coded and turbo detected systems to give all-inclusive information for researchers, engineers and students * Details EXIT-chart based irregular transceiver designs * Uses rich performance comparisons as well as diverse near-capacity design examples

Cover of OFDM and MC-CDMA for Broadband Multi-User Communications, WLANs and Broadcasting
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. 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 technical in--depth book is unique in its detailed exposure of OFDM, MIMO--OFDM and MC--CDMA. A further attraction of the joint treatment of these topics is that it allows the reader to view their design trade--offs in a comparative context.
Divided into three main parts: Part I provides a detailed exposure of OFDM designed for employment in various applications Part II is another design alternative applicable in the context of OFDM systems where the channel quality fluctuations observed are averaged out with the aid of frequency--domain spreading codes, which leads to the concept of MC--CDMA Part III discusses how to employ multiple antennas at the base station for the sake of supporting multiple users in the uplink* Portrays the entire body of knowledge currently available on OFDM* Provides the first complete treatment of OFDM, MIMO(Multiple Input Multiple Output)--OFDM and MC--CDMA* Considers the benefits of channel coding and space time coding in the context of various application examples and features numerous complete system design examples* Converts the lessons of Shannon's information theory into design principles applicable to practical wireless systems* Combines the benefits of a textbook with a research monograph where the depth of discussions progressively increase throughout the book This all--encompassing self--contained treatment will appeal to researchers, postgraduate students and academics, practising research and development engineers working for wireless communications and computer networking companies and senior undergraduate students and technical managers.
