Performance Comparison of Distributed Cooperative STBC and CDD MC-CDMA Multi-Hop Relaying Systems

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).
