Improving Performance of the Asynchronous Cooperative Relay Network with Maximum Ratio Combining and Transmit Antenna Selection Technique
In this paper, a new amplify and forward (AF) asynchronous cooperative relay network using maximum ratio combining (MRC) and transmit antenna selection (TAS) technique is considered. In order to obtain a maximal received diversity gain, the received signal vectors from all antennas of the each relay node are jointly combined by MRC technique in the first phase. Then, one antenna of each relay node is selected for forwarding MRC signal vectors to the destination node in the second phase.
