This letter investigates the performance of the satellite-terrestrial networks (STN), where a satellite tries to transmit information to a ground user through the help of multiple decode-and-forward relays and the existence of co-channel interference sources. In particular, the full-duplex technique and partial relay selection are applied at the relay to increase the total throughput at the destination, enhance the system reliability, and reduce the complexity. In this context, the outage probability (OP) is computed in a closed-form expression. Numerical results are provided to confirm the accuracy of the proposed mathematical framework. Our findings illustrate that the outage performance can be effectively enhanced by increasing either number of relays or transmit power.

具有同信道干扰的卫星地面全双工中继网络的中断性能

这封信调查了卫星地面网络 (STN) 的性能，其中卫星试图通过多个解码转发中继和同信道干扰源的存在向地面用户传输信息。特别是在中继端采用全双工技术和部分中继选择，以增加目的地的总吞吐量，增强系统可靠性，降低复杂度。在这种情况下，中断概率 (OP) 以封闭式表达式计算。提供了数值结果以确认所提出的数学框架的准确性。我们的研究结果表明，可以通过增加中继数量或传输功率来有效提高中断性能。
