Interference management in wireless communication systems

Abstract

Interference management is the most important issue in wireless communication. Recently, many effective schemes to reduce the effects of interference are suggested. Interference Alignment(IA) is one of the key techniques which can be optimal with respect to Degrees Of Freedom(DOF). However, there are some practical issues, for example, global channel knowledge and infinite channel extension. In this thesis, we are going to suggest a simple scheme that do not need global channel knowledge and channel extension, also it can reduce interference and achieve better performance by introducing finite feedback and cooperation through a relay.
