Swarm intelligent distortionless energy Efficient techniques for cooperative mim af systems

Abstract

Energy Efficiency (EE) is an important design standard formulated for the communication systems of the future generation. In a similar manner, cooperative communication is hugelyeffective inboosting the performance of such kind of systems. The research carried out presently introduces a relay precoding optimization algorithm with the aim of resolving the EE problem in the Multiple-Input-Multiple-Output Amplify-And-Forward (MIMO-AF) Relay Networks having the correct Channel State Information (CSI). MIMO- AF system under Partial Channel State Information (PCSI) becomes a very difficult task.However, still there are many difficulties in realizing a MIMO- AF system, and one of these is high Peak-to-Average Power Ratio (PAPR), which results in serious nonlinear signal distortion and power inefficiency of the Power Amplifier (PA). newline
