In this work, performance of a multiple-input multiple-output dual hop amplify-and-forward relay network, where transmit antenna selection is employed at source and relay for transmission, and receive antenna selection and maximal ratio combining are employed at the relay and destination, respectively for reception, is analyzed over flat and asymmetric Nakagami-m fading channels. In the network, the source communicates with the destination by the help of single relay without source-destination link. The relay applies amplify-and-forward protocol to forward the signal transmitted by the source to the destination. In this paper, we derive closed-form cumulative distribution function, moments and moment generating function of end-to-end signal-to-noise ratio and closed-form symbol error probability expressions for fixed relay gain. We also derive the asymptotical outage probability and symbol error probability expressions to obtain diversity order of the network. Analytical results are validated by the Monte Carlo simulations.
