  • 摘要: 该文针对地面中继辅助的星地融合网络(ISTNs),分析了卫星采用不同解码方案时系统性能的差异。首先,提出一种新颖的用户配对方案,通过位置信息将卫星波束覆盖范围内的多个用户分为若干个组。接着,为了提高传输可靠性以及频谱利用率,用户采用混合多址接入技术与卫星进行通信。进一步,在考虑用户-地面中继链路服从Nakagami-m分布,地面中继-卫星链路服从相关阴影莱斯分布的情况下,分别推导出基于连续干扰消除(SIC)和联合解码(JD)两种解码方案的系统中断概率和吞吐量的闭合表达式。最后,计算机仿真验证了理论分析的正确性和所提方案相比正交多址(OMA)方案的优越性,并揭示了JD解码技术在ISTNs中的可行性。
