Abstract :
In this letter, we investigate the performance of multiple input multiple output (MIMO) amplify-and-forward (AF) relay network over Rayleigh-Rician asymmetric channel with antenna correlation. We consider multiple correlated antennas at all nodes and general correlation matrices are assumed with arbitrary eigenvalue distribution. Specifically we derive the outage probability and the average symbol error rate (SER) for end-to-end signal-to-noise ratio (SNR). Moreover, simple asymptotic results are derived in high SNR in order to obtain the diversity gain variation. Finally, Monte Carlo simulations verify the accuracy of the analytical results.
