Emulating Fast-Fading Rician Wireless Environments with Electronically Adjustable K-Factors in a Programmable-Metasurface-Stirred Reverberation Chamber
Résumé
Experimentally emulating the wireless test environments typically considered in signal processing can be challenging, especially for MIMO communications under Rician fast-fading if the K-factor is supposed to be adjustable. We demonstrate experimentally that electronic stirring of a reverberation chamber with a programmable metasurface conveniently enables the implementation of such channel conditions. We carefully characterize the precision with which a desired K-factor can be implemented simultaneously across multiple antenna pairs. © 2023, META Conference. All rights reserved.
