Cooperative Diversity Performance of SISO Relaying Channel for Mobile Networks

In wireless communications system attenuation and fading limit the channel capacity of a communications link. Cooperative diversity is a transmission technique to overcome fading, multipath and inter-channel interference. As an important part of "spatial diversity" systems, cooperative diversity involving multi hop data relays is a solution to improve propagation performance, expanding coverage and enhancing system capacity in such wireless environments. In a cooperative diversity system, the "third party" mobile devices acting as relays to help the main transmission link for improving the performance such as bit error rate (BER), data rate, coverage. This paper is a study of analyzing the system performance for SISO-Relaying SISO and in different wireless channel and results show the better performance of cooperative communication.
