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...
Distributed Cooperative Cyclic Delay Diversity (DCCDD) multi-hop relay network is shown to yield superior performance over traditional link network. The benefits provided by increased frequency selectivity caused by the cyclic delays are evaluated through the explicit closed-form BER expressions and maximum achievable throughput [bits/s/Hz]. Towards that end resource allocation strategies in terms...
