This Book is part 2 and broadly addresses two research problems in MIMO with OFDM system namely PAPR and ICI. The fundamental techniques of MIMO OFDM systems were given in Chapter-1. The concept of PAPR in OFDM signals and PAPR reduction techniques have been investigated. Chapter-2 describes PAPR reduction techniques like precoding, distortionless and distortion techniques. Chapter-3 addresses the carrier frequency offset estimation and ICI reduction techniques. Chapter-4 describes SFBC-MIMO-OFDM SYSTEM MODEL-RECEIVER STRUCTURES and IC receiver model. Chapter-5 presents ICI Self-Cancellation With Cosine Windowing In Ofdm Transmitters Over Fast Time-Varying Channels.
