Secrecy performance of two‐way integrated satellite terrestrial relay networks with multiple users

Abstract

This letter studies the secrecy performance for a two-way integrated satellite terrestrial relay networks. Particularly, multiple legitimate users along with maximal user scheduling scheme are applied in the considered networks. In addition, the closed-form expression for the secrecy outage probability of the considered two-way networks is obtained. Moreover, to investigate the impacts of the system parameters on the secrecy performance in high signal-to-noise ratio regime, the asymptotic analysis for the secrecy outage probability is further derived. Finally, Monte Carlo simulation results are provided to prove the theoretical results.

Novel semi-blind amplify-and-forward strategy of two-way hybrid satellite-terrestrial relaying network

“…The hybrid satellite-terrestrial relaying network is a promising and attractive infrastructure for future communication networks due to the benefits of providing navigation assistance, wide coverage, and services in tunnel areas, thus attracting much attention from the research community [1][2][3][4][5] . Of particular interest is two-way hybrid satellite-terrestrial relaying networks, which can overcome the loss in spectral efficiency due to half-duplex transmission [6][7][8] . In particular, considering the practical application of the network, the traditional CSI-assisted AF strategy [6][7] is adopted, which requires relay to attain the instantaneous CSI of two source-relay links and estimate the instantaneous source-relay channel amplitude continuously.…”
