摘　　要：对车联网场景下通信、感知和计算融合的性能进行分析。对于通感一体化(ISAC)上行链路,通过分析分集阶数和高信噪比(SNR)斜率来评估通信和速率(CMR)和感知速率(SR),同时推导了通信和速率(CMR)、感知速率(SR)和计算和速率(CPR)的一般形式。此外,对可实现的上行CMR-SR-CPR区域进行表征。仿真结果表明,通信、感知和计算融合可以为CMR、SR和CPR提供比传统的频分通信感知和计算系统更高的增益。This paper analyzes the performance of integrated sensing,communication,and computing in vehicular network scenarios.Focusing on the integrated sensing and communication(ISAC)uplink,we evaluate the communication sum rate(CMR)and sensing rate(SR)by analyzing the diversity order and the slope at high signal-to-noise Ratio(SNR).Furthermore,we derive general expressions for CMR,SR,and computing sum rate(CPR).Additionally,we characterize the achievable uplink region for CMR-SR-CPR.Simulation results indicate that integrated sensing,communication,and computing provides higher gains for CMR,SR,and CPR compared to traditional frequency-division systems for communication,sensing,and computing.
