  • 摘要: 为满足日益增长的高效通信和可靠感知需求,该文提出可重构智能超表面(RIS)辅助无线携能通信(SWIPT)-非正交多址接入(NOMA)系统,该系统同时实现目标感知和信息传输。考虑非完美连续干扰消除(SIC)和信道估计误差(CEE)两种非理想因素,分析了所提系统的可靠性、有效性以及雷达感知性能,分别推导出系统中断概率(OP)、遍历速率(ER)、检测概率(PoD)以及雷达估计信息速率(REIR)的解析表达式。分析结果表明:非完美SIC和CEE对系统的性能有负面影响;中断概率随基站发射功率的增大而减小,在高信噪比区域趋于定值;遍历速率及雷达估计信息速率随基站发射功率增大而增加,在高信噪比区域稳定于一个上限值;在不同的检测阈值下,检测概率随基站发射功率的增大而增大;联合雷达检测和通信覆盖概率(JRDCCP)分别随中断阈值和检测阈值的升高而降低。
