Providing a comprehensive introduction to the basic principles, design techniques and analytical tools of wireless communications, this book focuses primarily on the design of practical systems. Following an overview of wireless systems and standards, the characteristics of the wireless channel are described, including capacity limits. Various modulation and coding schemes are then discussed in detail, and include state-of-the-art adaptive modulation and diversity techniques. The concluding chapters cover multiple and random access in wireless networks, cellular system design, and ad-hoc network design.
