Abstract :
The performance of multi-hop multiple-input, multiple-output (MIMO) communication scenarios is evaluated for space time block coded (STBC) and the proposed distributed cyclic delay diversity (CDD) technique. By increasing the frequency selectivity, multi-stage CDD with low complexity implementation yields significant performance improvement as relaying network. Both diversity techniques based on frequency-correlated MC-CDMA subcarriers networks are investigated by using the moment generating function (MGF) over correlated Nakagami-m fading channels .The system performance evaluation is provided for the exact average symbol error rate (SER) and the end-to-end bit error rate (BER). In order to maximize the end-to-end throughput [bits/s/Hz], explicit allocations strategies are derived and analyzed. Simulation results are also presented which show excellent agreement with the analytical framework.
