In this letter, we investigate the performance of multiple-input multiple-output techniques in a vehicle-to-vehicle communication system. We consider both transmit antenna selection with maximal-ratio combining and transmit antenna selection with selection combining. The channel propagation model between two vehicles is represented as n*Rayleigh distribution, which has been shown to be a realistic model for vehicle-to-vehicle communication scenarios. We derive tight analytical expressions for the outage probability and amount of fading of the post-processing signal-to-noise ratio.
