摘要

针对上行链路车联网环境下可重构智能反射面（RIS）辅助多用户的信道估计问题，提出了一种基于位置信息辅助的压缩感知信道估计算法。首先，基于通信设备位置信息，搭建单RIS辅助单用户通信模型，根据波束出发角（AOD）与到达角（AOA）的逻辑关系推导了最优相移矩阵，然后根据获得的相移矩阵，基于压缩感知理论构建了感知矩阵并进行信道估计，最后扩展到多用户场景下迭代求解。基于车联网技术获得的位置信息求解最优RIS相移矩阵，减少了信道额外的训练开销，进一步降低了信道估计的复杂度。仿真结果表明，所提算法具有较高的信道估计性能。

Abstract

Aiming at the problem that multi-user channel estimation assisted by reconfigurable intelligent surface (RIS) in the uplink Internet of vehicles environment

a location assisted compressive sensing channel estimation algorithm was proposed.Based on the location information of the communication equipment

a single RIS-assisted single-user communication model was built

and the optimal phase shift matrix was derived according to the logical relationship between the beam angle of departure (AOD) and the angle of arrival (AOA).The perception matrix was constructed and channel estimation was performed

and finally it was extended to multi-user scenarios and solved iteratively.The optimal RIS phase shift matrix was solved based on the position information obtained by the Internet of vehicles technology

which reduced the additional training overhead of the channel and further reduces the complexity of the channel estimation.Simulation results show that the proposed algorithm based on location information has high channel estimation performance.
