In this paper, the outage probability analysis of two-hop amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay networks is presented. The source and the destination are equipped with multiple antennas and communicate with each other, with the help of a single antenna relay which is subject to interference. Two systems are considered; transmit antenna selection with maximal ratio combining (TAS/MRC) and transmit antenna selection with selection combining (TAS/SC). We derive closed form expressions for the cumulative distribution function (CDF) for an arbitrary number of interferences under flat Rayleigh fading channels. Analytical and Monte Carlo simulation results are presented to validate the analysis and to demonstrate the effect of interference.
