Efficient Approach for Evaluating Throughput of Multi-Hop MIMO Amplify-and-Forward Relays

We present an effective throughput (or mutual information) evaluation approach for multi-hop multiple-input multiple-output amplify-and-forward relay channels with perfect channel state information at all transmission terminals. Simulated results indicate that the proposed approach is accurate and superior to those presented in existing works. This efficient and highly accurate approach is particularly useful for the development of complex system level simulators.
