Selective PNC in Satellite-Terrestrial Network over Non-Identical Fading Channels
文献摘要：
We analyze the performance of a two-way satellite-terrestrial decode-and-forward(DF)re-lay network over non-identical fading channels.In particular,selective physical-layer network coding(SPNC)is employed in the proposed network to im-prove the average end-to-end throughput performance.More specifically,by assuming that the DF relay performs instantaneous throughput comparisons be-fore performing corresponding protocols,we derive the expressions of system instantaneous bit-error-rate(BER),instantaneous end-to-end throughput,average end-to-end throughput,single node detection(SND)occurrence probability and average end-to-end BER over non-identical fading channels.Finally,theoret-ical analyses and Monte Carlo simulation results are presented.Evaluations show that:1)SPNC protocol outperforms the conventional physical-layer network coding(PNC)protocol in infrequent light shadowing(ILS),average shadowing(AS)and frequent heavy shadowing(FHS)Shadowed-Rician fading channels.2)As the satellite-relay channel fading gets more se-vere,SPNC protocol can achieve more performance improvement than PNC protocol and the occurrence probability of SND protocol increases progressively.3)The occurrence probability increase of SND has a beneficial effect on the average end-to-end throughput in low signal-to-noise ratio(SNR)regime,while the occurrence probability decrease of SND has a bene-ficial effect on the average end-to-end BER in high-SNR regime.
