摘要

低地球轨道卫星（LEOS）通信已成为实现全球覆盖的一项前景广阔的技术，同时通过在低地球轨道卫星之间建立通信链路进一步减少了端到端延迟。本文分析了多跳 LEOS 网络在射频/自由空间光学（FSO）混合链路上的误码率（BER）和中断概率性能，其中射频链路用于地面终端和 LEOS 之间的链路，FSO 链路用于建立卫星间链路（ISL）。我们通过蒙特卡罗模拟证实了得出的闭式结果，并通过比较有 ISL 和无 ISL 的情况，展示了卫星跳数对中断概率和平均误码率性能的影响。

Performance analysis of multi-hop low earth orbit satellite network over mixed RF/FSO links

Low earth orbit satellite (LEOS) communication has emerged as a promising technology to achieve global coverage, while further reducing the end-to-end latency by establishing communication link between LEOSs. In this paper, we analyze the performance of multi-hop LEOS network in terms of bit error rate (BER) and outage probability over mixed radio frequency (RF)/free space optical (FSO) links where RF link is used for the link between ground terminal and LEOS and FSO link is used for establishing inter-satellite links (ISLs). The derived closed-form results are confirmed via Monte Carlo simulations and we show the effect of the number of satellite hops on outage probability and average BER performance by comparing scenarios both with and without ISLs.
