Year: 2025

Type: article

Abstract: This paper investigates methods to enhance antenna's channel information extraction capabilities in wireless communications, particularly in challenging multi‐path environments. Focusing on the issues of channel information loss due to multi‐path superposition at the receiver and multi‐path fading during wireless channel propagation, this paper utilizes metasurface antennas to rapidly reconfigure antenna patterns and construct high‐dimensional projection spaces, thus improving information sensing resolution. Based on this, a channel‐matched receiving pattern design method is proposed to mitigate the communication performance loss caused by multi‐path fading. Furthermore, this paper analyses the comprehensive impact of various metasurface parameters on the performance of the proposed scheme, providing theoretical guidance for engineering implementation. Simulation results demonstrate that the proposed scheme can achieve the performance of multi‐path channel estimation and reception close to those of multi‐antenna arrays using a single radio frequency link.
