Chongjun Ouyang, Yuanwei Liu, Hongwen Yang

摘要:

分析了多输入多输出下行链路综合传感通信系统(ISAC)的传感通信性能。分析了三种ISAC方案,包括以感知为中心的设计、以通信为中心的设计和帕累托最优设计。对于每种情况下,多样性的订单和高信噪比斜率的传感速率(SR)和通信速率(CR)的推导,以获得进一步的见解。数值结果表明:\romannumeral 1)ISAC与现有频分S\&C(FDSAC)技术具有相同的分集阶数; \romannumeral 2)ISAC比FDSAC具有更大的高信噪比斜率和更宽的SR-CR区域。

英文摘要:

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.
