A multi-user full-duplex (FD) two-way relaying system is considered with decode-and-forward relaying protocol. All nodes are assumed to have FD abilities, and residual selfinterference (RSI) at each node is modeled as a Rician distributed random variable. Based on the availability of channel state information (CSI) at the relay node, different scheduling schemes are adopted and investigated in terms of outage probability. For the blind case when CSI is unavailable, the random scheduling is analyzed. In the presence of CSI, the absolute channel power based scheduling and normalized channel power based scheduling schemes are considered. A precise closed-form expression for the outage probability is derived for independent and non-identically distributed channels. The theoretical results are verified through Monte-Carlo simulations.

具有 Rician 分布式 RSI 的全双工多用户中继系统的中断性能

多用户全双工（FD）双向中继系统被认为具有解码转发中继协议。假设所有节点都具有 FD 能力，并且每个节点的残余自干扰 (RSI) 被建模为 Rician 分布式随机变量。基于中继节点的信道状态信息（CSI）的可用性，采用不同的调度方案并在中断概率方面进行研究。对于CSI不可用的盲情况，分析随机调度。在存在CSI的情况下，考虑了基于绝对信道功率的调度和基于归一化信道功率的调度方案。对于独立和非相同分布的信道，可以导出中断概率的精确封闭形式表达式。通过蒙特卡罗模拟验证了理论结果。
