In this paper, we evaluate performance of ANC based MIMO cooperative relaying network over Nakagami-m fading channel. In the considered scenario, a source terminal transmits symbols with the help of one or multiple intermediate relays to a destination. The source and destination nodes contain one antenna whereas relay terminals contain two antennas. Relay terminals operate in amplify-and-forward (AF) relaying mode. Alamouti coding scheme is also used at the relays to improve the overall system performance. All the received symbols are combined at the destination using maximal ratio combining (MRC) technique. Moment generating function (MGF) based approach is followed to deduce the closed form symbol-error-rate (SER) expression. We investigate the performance of the system in terms of SER over Nakagami-m fading environment. A closed matched is observed in the analytical and simulation results.
