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.

Multi-Carrier Direct-Sequence Code Division Multiple Access (MC-DS-CDMA) is a multiplexing technique that combines the advantages of both multi-carrier modulation and DS-CDMA. Among them are high system flexibility, high data rate transmission, high bandwidth efficiency and fading resilience. Adopted as an option for the down-link transmission in the CDMA2000 third Generation (3G) cellular standard, MC-DS-CDMA is also one of the potential candidates for the future fourth Generation (4G) broadband wireless systems. When designing receivers for MC-DS-CDMA mobile wireless systems, two main problems must be taken into account. Firstly, the Multiple Access Interference (MAI) caused by other active users greatly limits the system capacity. Secondly, the multi-path fading of mobile radio channels which highly degrades the system performance. Therefore, in this book, our objective is twofold. Firstly, we aim at designing new receivers for MC-DS-CDMA systems that are able to suppress the MAI. Secondly, as receiver design usually requires the explicit channel estimation, we intend to develop new techniques to estimate time-varying fading channels.
