提出PASS-QRSMA-ISAC框架，结合夹持天线与正交速率分割多址，实现双室内多用户通信与感知，通过统计表征和仿真验证，优于现有基准方案。
AI 中文摘要
本文提出了一种夹持天线系统（PASS）辅助的下行正交速率分割多址（Q-RSMA）集成感知与通信（PASS-QRSMA-ISAC）框架，用于同时支持多用户通信和目标感知。在所提出的框架中，沿介质波导部署的多个夹持天线（PA）为分布在双房间室内环境中的通信用户（CU）提供服务，其中视距（LoS）和非视距（NLoS）传播条件共存。通过将PASS与Q-RSMA集成，所提出的框架改善了干扰管理，同时降低了对连续干扰消除的依赖。建立了通信和感知信号模型，随后给出了相应的信噪比/信干噪比表达式。为了获得可处理的解析见解，首先分析了理想波导条件下的两用户单PA情况，其中利用距离统计、CDF/CCDF表征和数值积分方法，推导了每用户通信中断概率（COP）、系统COP、感知中断概率（SOP）和遍历和速率。随后，通过为LoS通信、NLoS通信和感知信道建立统计表征，将分析扩展到广义的多用户多PA场景。基于这些表征，针对广义框架推导并评估了每用户COP、系统COP、SOP和遍历和速率。蒙特卡洛仿真验证了解析结果，并展示了所提出的PASS-QRSMA-ISAC框架相对于所考虑的基准方案（包括PASS-RSMA-ISAC、PASS-NOMA-ISAC和PASS-SDMA-ISAC）的性能增益。结果进一步突出了各种系统参数对所提出框架的影响。
英文摘要
This paper proposes a pinching antenna system (PASS)-assisted downlink quadrature rate-splitting multiple access (Q-RSMA)-based integrated sensing and communication (PASS-QRSMA-ISAC) framework for simultaneously supporting multi-user communication and target sensing. In the proposed framework, multiple pinching antennas (PAs) deployed along a dielectric waveguide serve communication users (CUs) distributed across a dual-room indoor environment, where line-of-sight (LoS) and non-line-of-sight (NLoS) propagation conditions coexist. By integrating PASS with Q-RSMA, the proposed framework improves interference management while reducing the dependence on successive interference cancellation. The communication and sensing signal models are developed, followed by the corresponding SNR/SINR expressions. To obtain tractable analytical insights, a two-user single-PA case under ideal waveguide conditions is first analysed, where the per-user communication outage probability (COP), system COP, sensing outage probability (SOP), and ergodic sum-rate are formulated using distance statistics, CDF/CCDF characterisations, and numerical integration methods. The analysis is then extended to the generalised multi-user multi-PA scenario by developing statistical characterisations for the LoS communication, NLoS communication, and sensing channels. Based on these characterisations, the per-user COP, system COP, SOP, and ergodic sum-rate are formulated and evaluated for the generalised framework. Monte Carlo simulations validate the analytical results and demonstrate the performance gains of the proposed PASS-QRSMA-ISAC framework over the considered benchmark schemes, including PASS-RSMA-ISAC, PASS-NOMA-ISAC, and PASS-SDMA-ISAC. The results further highlight the effects of various system parameters on the proposed framework.
