论文摘要
本文分析了通过多输入多输出下行链路集成S \＆C（ISAC）系统实现的传感和通信的性能（S \＆C）。分析了三种ISAC场景，包括以感官为中心的设计，以通信为中心的设计和帕累托最佳设计。对于每种情况，传感速率（SR）和通信率（CR）的多样性顺序和高信噪比斜率被得出以获得进一步的见解。数值结果表明，\ romannumeral1）ISAC达到的多样性顺序与现有的频率S \＆C（FDSAC）技术相同； \ romannumeral2）ISAC比FDSAC实现了更大的高SNR斜率和更广泛的SR-CR区域。
This article analyzes the performance of sensing and communications (S\&C) achieved by a multiple-input multiple-output downlink integrated S\&C (ISAC) system. Three ISAC scenarios are analyzed, including the sensing-centric design, communications-centric design, and Pareto optimal design. For each scenario, diversity orders and high signal-to-noise ratio slopes of the sensing rate (SR) and communication rate (CR) are derived to gain further insights. Numerical results reveal that \romannumeral1) ISAC achieves the same diversity order as existing frequency-division S\&C (FDSAC) techniques; \romannumeral2) ISAC achieves larger high-SNR slopes and a broader SR-CR region than FDSAC.
