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.

Currently, a technical in-depth book on this subject is
unavailable, which has a similar 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

By providing an all-encompassing self-contained treatment this
volume will appeal to a wide readership, as it is both an
easy-reading textbook and a high-level research monograph.

Klappentext
This concise volume provides a widely accessible introduction to OFDM and MC-CDMA. Based on the authors' experience in researching OFDM in the context of various applications, it systematically converts the lessons of Shannon's information theory into practical wireless system design examples. Comprehensive coverage of OFDM, MIMO-OFDM and MC-CDMA is presented, incorporating radically new research-oriented principles. A further strength of this primer is that it considers the ambitious aim of achieving near-maximum-likelihood multi-user MIMO-OFDM performance at a modest complexity, proposing an advanced extension of the Complex Sphere Detector (CSD). This technique allows the system to support a higher number of OFDM/MC-CDMA users than the number of antennas even in the case of high-throughput QAM schemes.

• The design and performance of OFDM modems are highlighted, covering both Gaussian and wideband fading channels, frequency domain synchronization as well as adaptive single- and multi-user OFDM
• Offers a comparative study of OFDM and MC-CDMA, discussing spreading sequences, adaptive modulation and the attainable performance in synchronous environments
• Contains an advanced section on genetic algorithm aided joint multi-user channel estimation techniques for multi-user SDMA-OFDM
• Introduces an avant-garde design principle, which aims for directly minimizing the bit error ratio (BER) at the output of the multi-user OFDM system

As an introductory treatment of the complex subject of OFDM, this primer text will be attractive to a wide readership, including postgraduate students, systems and development engineers, as well as communications managers and practitioner.
