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. <p>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.</p> <p>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. </p> <p>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. </p> <p>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.</p> <p><u>Divided into three main parts:</u></p> <p><b>Part I</b> provides a detailed exposure of OFDM designed for employment in various applications</p> <p><b>Part II</b> 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</p> <p><b>Part III</b> discusses how to employ multiple antennas at the base station for the sake of supporting multiple users in the uplink</p> <ul type=”disc”> <li>Portrays the entire body of knowledge currently available on OFDM</li> <li>Provides the first complete treatment of OFDM, MIMO(Multiple Input Multiple Output)-OFDM and MC-CDMA</li> <li>Considers the benefits of channel coding and space time coding in the context of various application examples and features numerous complete system design examples</li> <li>Converts the lessons of Shannon’s information theory into design principles applicable to practical wireless systems</li> <li>Combines the benefits of a textbook with a research monograph where the depth of discussions progressively increase throughout the book</li> </ul> <p>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.</p>
