论文摘要
这封信分析了上行链路集成传感和通信(ISAC)系统的性能,在该系统中,通信用户(CUS)和雷达目标(RTS)共享相同的频段。 ISAC系统的通信过程中采用了非正交多访问(NOMA)协议。新的表达方式是为了表征停电概率,千古通讯速率和传感速率。此外,阐明了多样性顺序和高信噪比(SNR)斜率以获得进一步的见解。已经发现,在达到相同的通信速率时,ISAC系统的传感速率比传统的频率传感和通信(FDSAC)系统具有更高的感应速率,在该系统中,CUS和RTS共享孤立的频段。所有结果均通过数值模拟验证,并且非常同意。
This letter analyzes the performance of uplink integrated sensing and communications (ISAC) systems where communication users (CUs) and radar targets (RTs) share the same frequency band. A non-orthogonal multiple access (NOMA) protocol is adopted in the communication procedure of the ISAC system. Novel expressions are derived to characterize the outage probability, ergodic communication rate, and sensing rate. Besides, the diversity order and high signal-to-noise ratio (SNR) slope are unveiled to gain further insights. It is found that when achieving the same communication rate, the ISAC system enjoys a higher sensing rate than the conventional frequency-division sensing and communications (FDSAC) system where CUs and RTs share isolated bands. All the results are validated by numerical simulations and are in excellent agreement.
