Abstract

Integrated sensing and communications (ISAC) is a potential technology of 6G, aiming to enable end-to-end information processing ability and native perception capability for future communication systems. As an important part of the ISAC application scenarios, ISAC aided vehicle-to-everything (V2X) can improve the traffic efficiency and safety through intercommunication and synchronous perception. It is necessary to carry out measurement, characterization, and modeling for vehicular ISAC channels as the basic theoretical support for system design. In this paper, dynamic vehicular ISAC channel measurements at 28 GHz are carried out and provide data for the characterization of non-stationarity characteristics. Based on the actual measurements, this paper analyzes the time-varying PDPs, RMSDS and non-stationarity characteristics of front, lower front, left and right perception directions in a complicated V2X scenarios. The research in this paper can enrich the investigation of vehicular ISAC channels and enable the analysis and design of vehicular ISAC systems.

28ghz动态车载ISAC信道的非平稳性特性

集成传感与通信（ISAC）是6G的一项潜在技术，旨在为未来的通信系统提供端到端信息处理能力和本地感知能力。作为ISAC应用场景的重要组成部分，ISAC辅助车联网V2X （vehicle-to-everything， ISAC辅助车联网V2X）可以通过互联互通和同步感知来提高交通效率和安全性。有必要对车载ISAC通道进行测量、表征和建模，作为系统设计的基础理论支持。本文对28ghz的车载ISAC信道进行了动态测量，为非平稳特性的表征提供了数据。在实际测量的基础上，分析了复杂V2X场景下前、下前、左、右感知方向的时变pdp、RMSDS和非平稳性特征。本文的研究可以丰富车载ISAC通道的研究，为车载ISAC系统的分析和设计提供依据。
