Abstract :
The performance of a cooperative communication wireless network with a single relay system is studied over Nakagami-m fading channels. The simplest Alamouti space-time block code is transmitted through an amplify- and-forward (AF) relay terminal in a two-hop network. The exact symbol error rates (SER) are analyzed using the moment generating function (MGF) of the total signal to noise ratio (SNR) for a particular signal in the case of M-ary phase shift keying (M-PSK) modulation schemes. Subsequently, numerical and simulation results are provided to verify the accuracy of the formulation.
