Abstract
In this paper, we consider a multiuser hybrid satellite-terrestrial relay network (HSTRN) that employs opportunistic user scheduling with feedback latency and amplify-and-forward relaying with co-channel interference (CCI). The performance of the considered HSTRN may be critically affected by outdated channel state information (CSI) and CCI in practical operating environments. Leveraging the statistical characterizations of the underlying hybrid channels, we first derive a novel closed-form expression of outage probability of the considered system. Then, we derive an asymptotic outage expression to examine the achievable diversity order. Numerical and simulation results corroborate the analysis and illustrate the impact of outdated CSI and CCI on the HSTRN performance.
