Code-Division Multiplexing Using Space-Time-Coding Metasurface

Abstract Code-division multiplexing (CDM) is essential for supporting massive connectivity in wireless networks, but its implementation typically requires complex and costly radio-frequency (RF) chains. This work presents a simplified, low-cost wireless CDM system based on a space-time-coding metasurface (STCM).
