论文摘要
本文分析了多源集成传感和通信（ISAC）系统的性能，在该系统中，非正交多访问（NOMA）被利用以减轻用户间干扰。得出封闭形式的表达式以评估中断概率，千古通讯速率和传感速率。此外，进行了渐近分析以揭示多样性秩序和高信噪比（SNR）的高度斜率（SNR）。随着进一步的进一步，ISAC的可实现的感应通信率区域的特征是。事实证明，ISAC系统能够达到比常规频率传感和通信（FDSAC）系统更大的速率区域。
This paper analyzes the performance of a multiuser integrated sensing and communications (ISAC) system, where nonorthogonal multiple access (NOMA) is exploited to mitigate inter-user interference. Closed-form expressions are derived to evaluate the outage probability, ergodic communication rate, and sensing rate. Furthermore, asymptotic analyses are carried out to unveil diversity orders and high signal-to-noise ratio (SNR) slopes of the considered NOMA-ISAC system. As the further advance, the achievable sensing-communication rate region of ISAC is characterized. It is proved that ISAC system is capable of achieving a larger rate region than the conventional frequency-division sensing and communications (FDSAC) system.
