论文摘要
这封信分析了综合传感和通信（ISAC）系统的基本性能。对于下行链路和上行链路ISAC，分析了多样性顺序，以评估CR和传感速率（SR）的通信率（CR）和高信噪比（SNR）斜率。此外，可实现的下行链路和上行链路CR-SR区域的特征是。结果表明，与传统的频率传感和通信系统相比，ISAC可以为CR和SR提供更大的自由度，在这些频率下传感和通信系统分别用于传感和通信。
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.
