Research and Markets: Overview of the Majority of Single- and Multi-Carrier QAM Techniques.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c23053) has announced the addition of Quadrature Amplitude Modulation See QAM. Quadrature Amplitude Modulation - (QAM) A method for encoding digital data in an analog signal in which each combination of phase and amplitude represents one of sixteen four bit patterns. This is required for fax transmission at 9600 bits per second. : From Basics to Adaptive Trellis-Coded, Turbo-Equalised and Space-Time Coded OFDM (Orthogonal Frequency Division Multiplexing) A digital transmission technique that uses a large number of carriers spaced apart at slightly different frequencies. , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. and MC-CDMA MC-CDMA Multi-Carrier Code Division Multiple Access Systems, 2nd Edition to their offering. Motivated by the rapid evolution of the consecutive generations of wireless communication systems this volume continues to provide an overview of the majority of single- and multi-carrier QAM techniques. Now fully revised and updated, with more than 300 pages of new material, this new edition presents the wide range of recent developments in the field and places particular emphasis on the family of coded modulation aided OFDM and CDMA schemes. In addition, it also includes a fully revised chapter on adaptive modulation and a new chapter characterizing the design trade-offs of adaptive modulation and space-time coding. Divided into four parts: --Part I commences with a historical perspective and classic schemes for the uninitiated Part II - offers a deep discourse on adaptive QAM arrangements that have found their way also into the 3G systems High Speed Data Packet Access (HSDPA (High Speed Downlink Packet Access) See HSPA. ) mode --Part III - details the advanced intricacies of adaptive versus space-time block- and trellis-coded OFDM and MC-CDMA --Part IV - contains previously unpublished new research results. It commences with a theoretical chapter on the capacity of wireless channels. The discussions then continue by contriving sophisticated iterative coded modulation systems, such as TCM (1) (Trellis-Coded Modulation/Viterbi Decoding) A technique that adds forward error correction to a modulation scheme by adding an additional bit to each baud. TCM is used with QAM modulation, for example. , TTCM, BICM, BICM-ID BICM-ID Bit-Interleaved Coded Modulation with Iterative Decoding designed for turbo-detected QAM-based space-time coded OFDM and CDMA systems operating over wireless channels In summary, this volume amalgamates a comprehensive textbook with a deep research monograph on the topic of QAM, ensuring it has a wide-ranging appeal for both senior undergraduate and postgraduate students as well as practicing engineers and researchers.
