Peak Power Control In Multicarrier Communications

This page intentionally left blank PEAK POWER CONTROL IN MULTICARRIER COMMUNICATIONS The implementation of multicarrier (MC) modulation in wireless and wireline communication systems, such as OFDM and DMT, is restricted by peak signal power, due to a sensitivity of the technique to distortions introduced by nonlinear devices. By controlling the peak power, the negative influence of signals with high peaks on the performance of the transmission system is greatly reduced. This book describes the tools necessary for analyzing and controlling the peak-to-average power ratio in MC systems, and how these techniques are applied in practical designs. The author starts with an overview of MC signals and basic tools and algorithms, before discussing properties of MC signals in detail: discrete and continuous maxima; statistical distribution of peak power, and codes with constant peak-to-average power ratio are all covered, concluding with methods to decrease peak power in MC systems. Current knowledge, problems, methods, and definitions are summarized using rigorous mathematics, with an overview of tools for the engineer. This book is aimed at graduate students and researchers in electrical engineering, computer science, and applied mathematics, as well as practitioners in the telecommunications industry.
