摘要

针对现有通信感知一体化（integrated sensing and communication，ISAC）系统性能指标通用性较差以及无线信号传输过程中实际存在的残余硬件损伤问题，采用均方误差的统一性能分析框架，提出了一种在残余硬件损伤下支持上下行通信与目标感知的非正交多址接入（non-orthogonal multiple access，NOMA）辅助的ISAC系统模型。基于发送信号的最小均方误差扩展了中断概率（outage probability，OP）的定义以提供统一性能指标，推导了NOMA-ISAC系统的通信和感知用户的OP及渐近OP的解析表达式。仿真结果验证了NOMA-ISAC系统性能分析的正确性。实验结果表明：残余硬件损伤和不完美串行干扰消除会恶化NOMA-ISAC系统的通信和感知用户性能；通信用户和感知用户的OP均与相应链路的信噪比、均方误差阈值以及非理想因素系数有关，下行通信用户的OP还受功率分配因子的影响。

Abstract

Aiming at the problems of poor generality of performance metrics in existing integrated sensing and communication (ISAC) systems and the residual hardware impairments that actually exist in wireless signal transmission

by adopting a unified performance analysis framework based on mean square error

a non-orthogonal multiple access (NOMA)-assisted ISAC system model supporting both uplink and downlink communications as well as target sensing under residual hardware impairments was proposed. Based on the minimum mean square error of the transmitted signal

the definition of outage probability (OP) was extended to provide a unified performance metric

and the analytical expressions of OP and asymptotic OP for both communication and sensing users in the NOMA-ISAC system were derived. Simulation results verify the correctness of the performance analysis for the NOMA-ISAC system. Experimental results demonstrate that residual hardware impairments and imperfect successive interference cancellation will degrade the performance of both communication users and sensing users in the NOMA-ISAC system

and OP of both communication users and sensing users is related to the signal-to-noise ratio of the corresponding links

mean square error threshold

and non-ideal factor coefficients

while the OP of downlink communication users is also affected by the power allocation factor.
