摘要

通信感知一体化（integrated sensing and communication，ISAC）通过实现通信和雷达感知的资源共享，在人机交互、车联网（vehicle-to-everything，V2X）、遥感和环境检测等应用场景中很有前景。为解决高移动性的车联网中通信和雷达感知所需的频率资源的冲突，基于正交时频空间（orthogonal time frequency space， OTFS）调制提出了 OTFS-ISAC 系统，基站通过接收车辆反射的回波，获得车辆运动参数，从而建立车辆运动的移动拓扑模型。此外，针对多车辆移动场景，提出了保证用户公平性的非正交多址接入OTFS-ISAC系统设计和功率分配算法。仿真结果表明，相比于无雷达感知辅助的非正交多址OTFS系统，基于OTFS-ISAC的非正交多址接入系统实现了25%的信息速率提升。

Abstract

By sharing resources for radar sensing and communications

integrated sensing and communication (ISAC) has promising applications in diverse scenarios

such as human-machine interface

vehicle-to-everything (V2X)

remote sensing

and environment surveillance.In order to resolve the frequency resource conflict in high-speed V2X networks

based on the modulation orthogonal time frequency (OTFS)

the OTFS-ISAC system was proposed

where the base station receives reflected echoes to obtain sensing parameters of vehicle motion and then establish the vehicle’s mobile topology.Additionally

in terms of the multi-vehicle network

the design of OTFS-ISAC with NOMAsatisfying the fairness and the algorithm of power allocation were proposed.Simulations show that compared with the NOMA without radar sensing system

the proposed design improves the system data rate by 25%.
