In this paper, a multi-user full-duplex (FD) two-way relaying system with decode-and-forward protocol is considered where all the nodes are assumed to be mobile and to have FD abilities. The residual self-interference (RSI) at each node is modeled as a Rician distributed random variable and the effect of mobility is incorporated by adopting the first order auto-regressive (AR) model. Then, the signal-to-interference-plus-noise-ratio (SINR) based scheduling schemes namely random scheduling, absolute channel power-based (CPB) scheduling, hybrid scheduling, and normalized CPB scheduling, are modified and the user pair selection is carried out on the basis of instantaneous channel statistics. The performance of the considered framework is analyzed for the modified scheduling schemes in terms of error probability and average rate. Next, the closed-form expressions for the symbol error probability (SEP) and average rate are derived for independent and non-identically distributed Rayleigh fading channels. Also, the numerical analysis highlighting the impact of user mobility and imperfect channel estimation on the scheduling strategies, fairness is presented. Furthermore, the impacts of the degree of traffic asymmetry, scheduling fairness, user mobility, channel estimation errors and RSI on the system performance are investigated. Numerical results are validated through the Monte Carlo simulations.

基于Rician分布式RSI的多用户全双工双向中继系统的调度性能

在本文中，考虑了具有解码和转发协议的多用户全双工 (FD) 双向中继系统，其中假设所有节点都是移动的并具有 FD 能力。每个节点的残余自干扰 (RSI) 被建模为一个 Rician 分布式随机变量，并通过采用一阶自回归 (AR) 模型来合并移动性的影响。然后，修改基于信干噪比 (SINR) 的调度方案，即随机调度、基于绝对信道功率 (CPB) 调度、混合调度和归一化 CPB 调度，并且用户对选择为在瞬时信道统计的基础上进行。在错误概率和平均率方面分析了所考虑框架的性能，用于修改后的调度方案。下一个，符号错误概率 (SEP) 和平均速率的闭式表达式是针对独立和非相同分布的瑞利衰落信道推导出来的。此外，数值分析强调了用户移动性和不完善的信道估计对调度策略、公平性的影响。此外，还研究了流量不对称程度、调度公平性、用户移动性、信道估计误差和 RSI 对系统性能的影响。数值结果通过蒙特卡罗模拟得到验证。公平被提出。此外，还研究了流量不对称程度、调度公平性、用户移动性、信道估计误差和 RSI 对系统性能的影响。数值结果通过蒙特卡罗模拟得到验证。公平被提出。此外，还研究了流量不对称程度、调度公平性、用户移动性、信道估计误差和 RSI 对系统性能的影响。数值结果通过蒙特卡罗模拟得到验证。
