Performance of OSTBC MIMO amplify-and-forward two-hop relay system with asymmetric channels

Abstract

We present performance analysis of multiple input multiple output (MIMO) amplify-and-forward (AF) two-hop relay system having asymmetric independent channels of Nakagami-m fading and Rician fading. By considering channel state information (CSI)-assisted relaying, we derive outage probability, average symbol error rate (SER) and ergodic capacity. Further we provide high SNR results to understand the depth of system performance and diversity gain. Finally, we present Monte Carlo simulations to verify our analytical results.
