This book explores the different strategies regarding the feedback information for wireless communication systems. The text analyzes the impact of quantization and correlation of channel state information (CSI) on the system performance. The authors show the effect of the reduced and limited feedback information and gives an overview about the feedback strategies in the standards. This volume presents theoretical analysis as well as practical algorithms for the required feedback information at the base stations to perform adaptive resource allocation efficiently and mitigate interference coming from other cells. Analyzes the impact of feedback information on the capacity of different wireless communication systems Provides practical algorithms for feedback information in wireless communication systems Covers key aspects of wireless systems, for example investigating feedback strategies of single user, multi-user and multi-cell systems
