摘要

本文研究了全双工中继星-地系统的中断性能。该系统由一个卫星源、一个中继和两个用户组成。首先,卫星将两个用户的信息发送给FD中继,由FD中继解码后转发给两个用户。其中,采用非正交多址协议合并两个用户的信号。我们研究了继电器存在残余自干扰时的系统中断性能,并导出了两个用户的中断概率的精确表达式。通过蒙特卡罗仿真验证了所得结果的准确性。

Outage analysis for full-duplex relaying satellite-terrestrial NOMA systems
In this paper, the outage performance for a full-duplex (FD) relaying satellite-terrestrial system is investigated. The system consists of a satellite source, a relay, and two users. Firstly, the satellite transmits the information of two users to the FD relay, and then the relay decodes and forwards the information to both users. Herein, the non-orthogonal multiple access protocol is used to incorporate the signal of two users. We investigate the system outage performance in the presence of residual self-interference of the relay and derive the exact expressions of outage probability for two users. Moreover, the accuracy of the results is verified with Monte-Carlo simulations.
