Abstract:
In this paper, a dual-hop cooperative diversity land mobile satellite system (LMSS) respectively adopted amplify-and-forward (AF), decode-and-forward (DF), and coded cooperation (CC) relaying protocols is proposed, and the outage probability behaviors of the three protocols have been analyzed. We use the signal to noise ratio (SNR) of each path to derive the closed-form expressions of outage probability for each protocol. The accurately approximated expressions in favor of computation simplicity have also been derived applying trapezoidal integration. The Monte Carlo simulations show good match with the proposed analytical results under different shadowing environments, showing that CC is the best strategy for low terminal transmitting SNR. For high transmitting SNR, AF protocol outperforms the high cooperation level CC and DF, while the low cooperation level CC turns out to be better than the other two protocols.
