外文摘要：Communication and sensing are basically required in intelligent transportation.The combination of two functions can provide a viable way in alleviating concerns about resource limitations.To achieve this,we propose an integrated sensing and communication(ISAC)system based on cellular vehicle-to-everything(C-V2X).We first analyze the feasibility of new radio(NR)waveform for ISAC system.We discuss the possibility of reusing NR waveform for sensing based on current NR-V2X standards.Ambiguity function is calculated to investigate the sensing perform-ance limitation of NR waveform.A C-V2X-based ISAC system is then designed to realize the two tasks in vehicular network simultaneously.We formulate an integrated framework of vehicular communication and automotive sensing using the already-existing NR-V2X network.Based on the proposed ISAC framework,we develop a receiver algorithm for target detection/estimation and communication with minor modifications.We evaluate the performance of the proposed ISAC system with communication throughput,detection probability,and range/velocity estimation accuracy.Simulations show that the proposed system achieves high reliability communication with 99.9999％throughput and high accuracy sensing with errors below 1 m and 1 m/s in vehicle scenarios.
