Performance of Cooperative MIMO Relaying System Using Linear Pre-Coding

In this work, we consider a cooperative MIMO single relay system using linear pre-coding at the source and relay in order to provide transmit spatial diversity gains. For this system, we evaluate the average bit error rate (BER) performance of the system by considering zero-forcing (ZF) equalization at the relay and the destination nodes. The impact of the use of pre-coding and number of antennas on the BER performance analyzed by means of computer simulation results for some system configurations.
