“…Various techniques are discussed in [1], to improve the diversity gain of such cooperative networks. In [7], a cross-layer approach that combined AMC and cooperative ARQ is proposed for an efficient communication over Land Mobile Satellite Channel (LMSC). A comparison of ARQ technique through satellite and terrestrial cooperative terminals in downlink communication is investigated in [8].…”

In this study, the Symbol error rate (SER) performance of cooperative based downlink satellite system with single terrestrial relay is investigated by using amplify-and-forward cooperation protocol over non identical fading channels. A closed form expression of exact SER over non identical fading channels is derived for M-ary phase shift keying (M-PSK) and M-ary quadrature amplitude modulation (QAM). We have derived an expression of joint probability density function (PDF) of the relay channels which is used to obtain the SER expression. Statistical results of Land Mobile Satellite Channel (LMSC) are applied through numerical analysis to obtain the SER of the proposed system. It is shown that high cooperation gain is achieved at high SNR.Index Terms-Amplify-and-forward, Joint probability density function, Land mobile satellite channel, symbol error rate.
