Outage Probability Analysis For Hybrid Satellite And Terrestrial Network With Different Combining Schemes

In this paper, we investigate the outage probability (OP) of a hybrid satellite and terrestrial cooperative network (HSTCN) with the terrestrial relay having multiple antennas. Here, it is assumed that the satellite channel undergoes the shadowed-Rician fading, while terrestrial channel follows correlated Rayleigh fading. By supposing that statistic channel state information (CSI) of relay-destination link is available at the relay, we first obtain the end-to-end output signal-to-noise ratio (SNR) expression of the HSTCN. Then, the closed-form expressions of the outage probability for the considered system are derived, where two combining schemes, namely, selection combing (SC) and maximal-ratio combining (MRC) protocols are utilized at the destination to combine signals form the satellite and relay. Finally, numerical results are given to validity of the OP analysis, and reveal the performance difference of the two combining schemes.
