The performance of a two hop amplify-and-forward relay system, where the source-relay and the relay-destination channels experience Rayleigh and Rician fading, respectively, is investigated with relay selection. Partial relay selection is considered, where the relay is selected based on instantaneous and partial knowledge of the channel (source-relay). We derive an exact expression for the outage probability and a lower bound for the average bit error probability, where the bound becomes tight at medium to high signal-to-noise ratios. Also we provide simulation results to support the theoretical analysis.
