Abstract

Recent researches in Non-orthogonal multiple access (NOMA) have enabled radios to transmit and receive simultaneously at the same frequency using power domain multiplex. In addition, full duplex technology can also improve spectrum efficiency. Therefore, full duplex and NOMA are considered as potential candidates for next generation wireless networks. In this paper, we deploy system model based on stochastic geometry including full duplex base stations (BSs) and user equipment (UE) that are limited in half-full duplex mode. In the downlink NOMA, succession interference cancellation (SIC) error propagation model is considered to evaluate the system's coverage probability and average achievable rate. In uplink orthogonal multiplex access (OMA), the self-interference factor is considered to analyze the performance of uplink users due to the existence of full duplex BSs. The simulation results indicate that NOMA can improve the quality of services (QoS) of cell-edge users through power domain multiplexing, and the self-interference factor affects the overall performance of the full duplex system.

基于非正交多址的全双工网络性能分析

近年来，在非正交多址(NOMA)技术的研究中，利用功率域复用技术使无线电能够在同一频率上同时发射和接收。此外，全双工技术还可以提高频谱效率。因此，全双工和NOMA被认为是下一代无线网络的潜在候选者。在本文中，我们部署了基于随机几何的系统模型，包括半全双工模式下的全双工基站(BSs)和用户设备(UE)。在下行NOMA中，考虑了连续干扰抵消(SIC)误差传播模型来评估系统的覆盖概率和平均可达率。在上行正交多工接入(OMA)中，由于存在全双工bbs，考虑了自干扰因素来分析上行用户的性能。仿真结果表明，NOMA可以通过功率域复用提高蜂窝边缘用户的服务质量(QoS)，其自干扰因素影响全双工系统的整体性能。
