This letter analyzes the performance of a two‐hop MIMO multiuser relay network with a fixed gain amplify‐and‐forward protocol and antenna selection at the transmitter and receiver. A new expression for the cumulative distribution function of the highest instantaneous end‐to‐end signal‐to‐noise ratio is derived. Based on the above result, closed‐form expressions for outage probability and bit error rate are presented. Also, the diversity order of the system is determined. Finally, computer simulations are compared to the analytical results, and insights and observations are provided.
