The past decade has seen many advances in Wireless Communication theory and their implementation in Wireless systems. This textbook takes a unified view of the fundamentals of Wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in Digital Communication, Digital Signal Processing and OFDM Systems. Topics covered include OFDM, PAPR, Various PAPR Reduction techniques and their simulation results using MATLAB. An abundant supply of tables and figures reinforce the material in the text. This book is intended for use on graduate courses in Electronics and Communication engineering and will also be of great interest to practising engineers.
