This letter analyzes the fundamental performance of integrated sensing and communications (ISAC) systems. For downlink and uplink ISAC, the diversity orders are analyzed to evaluate the communication rate (CR) and the high signal-to-noise ratio (SNR) slopes are unveiled for the CR as well as the sensing rate (SR). Furthermore, the achievable downlink and uplink CR-SR regions are characterized. It is shown that ISAC can provide more degrees of freedom for both the CR and the SR than conventional frequency-division sensing and communications systems where isolated frequency bands are used for sensing and communications, respectively.

下行链路和上行链路综合传感与通信 (ISAC) 系统的性能



这封信分析了集成传感和通信(ISAC)系统的基本性能。对于下行链路和上行链路 ISAC,分析分集阶数以评估通信速率 (CR),并揭示 CR 和传感速率 (SR) 的高信噪比 (SNR) 斜率。此外,还描述了可实现的下行链路和上行链路 CR-SR 区域。结果表明,与传统的频分传感和通信系统(其中隔离频带分别用于传感和通信)相比,ISAC 可以为 CR 和 SR 提供​​更多的自由度。
