Abstract :
In this paper, we analyze the symbol error rate (SER) of a cooperative communication wireless network with a single relay system over independent and identical (i.i.d) Nakagami-m fading channels. The concept of the Alamouti code transmission technique is exploited with a two-stage protocol relay terminal operating in amplify-and-forward mode (AF). Taking these effects into account, the exact symbol error rates (SER) are determined 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.
