In the last decade, digital wireless communications have turned from a niche market into one of the most important industries. There has been an enormous growth in knowledge about this field and it is vital for all of today's communications engineers to have a thorough knowledge of digital wireless communications. Most existing textbooks or self-study books in this area do not seem to provide comprehensive coverage of the relevant topics - often related to the fact that they are up to five years old. Wireless Communications is a self-contained all encompassing current treatment of the area and topics covered will include directional channel modelling, multi-user detection, MIMO systems, and 3G standards. In addition, the author has combined mathematical derivations with intuitive explanations of the physical facts in order to help students (including self-study readers) to acquire a deeper understanding of the facts.
Provides a comprehensive and current treatment of a very hot topic, one of the fastest growing fields of communications Fills a gap in the market - offers a modern introductory textbook on the principles of mobile radio Combines mathematical derivations with thorough explanations of the physical facts This essential text is suitable for advanced undergraduate students (with a working knowledge of "standard" digital communications). Graduate students and practising engineers who want to learn the subject. Wireless communications engineers as a reference.
