• Sommario/riassunto: OFDM systems have experienced increased attention in recent years and have found applications in a number of diverse areas including telephone-line based ADSL links, digital audio and video broadcasting systems, and wireless local area networks. OFDM is being considered for the next-generation of wireless systems both with and without direct sequence spreading and the resultant spreading-based multi-carrier CDMA systems have numerous attractive properties.This volume provides the reader with a broad overview of the research on OFDM systems during their 40-year history.Part I commences with an easy to read conceptual, rather than mathematical, treatment of the basic design issues of OFDM systems. The discussions gradually deepen to include adaptive single and multi-user OFDM systems invoking adaptive turbo coding.Part II introduces the taxonomy of multi-carrier CDMA systems and deals with the design of their spreading codes and the objective of minimising their crest factors.This part also compares the benefits of adaptive modulation and space-time coding with the conclusion that in conjunction with multiple transmitters and receivers the advantages of adaptive modulation gradually erode both in OFDM and MC-CDMA systems.Part III addresses a host of advanced channel estimation and multi-user detection problems in the context of Space Division Multiple Access (SDMA) systems.Aimed at the mathematically advanced reader, this part provides a range of implementation-ready solutions, performance results and future research issues.Researchers, advanced students and practising engineers working in wireless communications will all find this valuable text illuminating and informative.
