In this work, unified performance analysis of multi-antenna dual-hop network with fixed relay gain and partial relay selection is studied over flat Nakagami-m fading channels. In considered scenarios, the source and destination communicate with help of a relay, which is selected from a group of relays, without direct source-to-destination link. The source, relays and destination are either equipped with single or multiple antennas. Maximal ratio transmission, transmit antenna selection and orthogonal space-time block coding are considered as transmission techniques at the source and relays. On the other hand, maximal ratio combining and selection combining are studied as reception techniques. Amplify-and-forward with fixed relay gain case is investigated. Outage probability, signal-to-noise ratio moments, moment generating function and symbol error probability expressions are derived to quantify the performance of the networks. Moreover, asymptotic outage probability and symbol error probability expressions are also derived to obtain diversity order. Analytical results are validated by Monte Carlo simulations.
