We present the performance analysis of a MIMO two hop beamforming amplify-and-forward (AF) fixed gain relay system with imperfect channel estimation. Imperfect channel state information(CSI) will degrade the performance of the system. Here we quantify this effect by deriving the exact outage probability and the symbol error rate(SER). To gain more insight, we also present an asymptotic analysis which provides the details of the diversity order.
