Space-Time Block Coding for Wireless Communications
Space-time coding is a technique that promises greatly improved performance in wireless communication systems by using multiple antennas at the transmitter and receiver. Space-Time Block Coding for Wireless Communications is an introduction to the theory of this technology. The authors develop the subject using a unified framework and cover a variety of topics ranging from information theory to performance analysis and state-of-the-art space-time block coding methods for both flat and frequency-selective fading multiple-antenna channels. They concentrate on key principles rather than specific practical applications, and present the material in a concise and accessible manner. Their treatment reviews the fundamental aspects of multiple-input, multiple-output communication theory, and guides the reader through a number of topics at the forefront of current research and development. The book includes homework exercises and is aimed at graduate students and researchers working on wireless communications, as well as practitioners in the wireless industry.
