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.
