Title
Outage Analysis And Optimization Of Noma-Based Integrated Satellite-Terrestrial System With An Af Relay
Abstract
In this paper, we investigate an integrated satellite-terrestrial system with non-orthogonal multiple access (NOMA) scheme, in which the satellite communicates with users through an amplify-and-forward (AF) relay. Perfect channel state information (CSI) is assumed to be unavailable and the impact of channel estimation is considered. Closed-form outage probability expression for each user is derived. To ensure fairness among users, a low-complexity power allocation algorithm for minimizing the maximum outage probability is proposed to find a suboptimal solution based on the asymptotic expression of outage probability. Numerical results are provided to validate the theoretical results and the superiority of the proposed NOMA scheme compared with orthogonal multiple access (OMA) scheme.
