Performance Study of a Cooperative Communication using Receive Antenna Selection and Transmit Beam-forming

Abstract

The work which we are presenting in this thesis consist of deep studies of cooperative communication. We investigate the outage probability of cooperative communication to examine its performance where source communicate with destination with the help of relay. This communication can be of one way or two way. We first derived end-to-end SNR for our proposed system and then we analyzed our system’s performance on the basis of the bit-error-rate (BER) and the expression of an outage probability. In Relay employed communication network, when relay except the signal from source then it follows a particular relaying protocol to transmit this received signal to destination. Mainly, decode-and-forward and amplify-and-forward protocol is used. We examine our system in a practical scenario effected by CEE and HI. We also introduced transmit beam-forming to extract more advantage of a multi user multi relaying network. We carried this analysis for Rayleigh type fading path only. In the hope of achieving better performance of relaying communication network, we introduced multiple user or multiple relay or combination of both. Further, presented asymptotic OP to examine the diversity order of our proposed system.
