Space-frequency-polarization-division multiplexed wireless communication system using anisotropic space-time-coding digital metasurface
文献摘要：
In the past few years,wireless communications based on digital coding metasurfaces have gained research interest owing to their simplified architectures and low cost.However,in most of the metasurface-based wireless systems,a single-polarization scenario is used,limiting the channel capacities.To solve the problem,multiplexing methods have been adopted,but the system complexity is inevitably increased.Here,a space-frequency-polarization-division multiplexed wireless communication system is proposed using an anisotropic space-time-coding digital metasurface.By separately designing time-varying control voltage sequences for differently oriented varactor diodes integrated on the metasurface,we achieve frequency-polarization-division multiplexed modulations.By further introducing different time-delay gradients to the control voltage sequences in two polarization directions,we successfully obtain space-frequency-polarization-division multiplexed modulations to realize a wireless communication system with a new architecture.The new communication system is designed with compact dual-polarized meta-elements,and can improve channel capacity and space utilization.Experimental results demonstrate the high-performance and real-time transmission capability of the proposed communication system,confirming its potential application in multiple-user collaborative wireless communications.
