Fig. 3: Space-time-coding metasurface (STCM)-based integrated sensing and communication (ISAC) system architecture.
From: Integrated sensing and communication based on space-time-coding metasurfaces
a Adjustable partitioning scheme of the STCM, which is divided into two regions for sensing and communication. The size of the two regions can be flexibly adjusted based on the required needs. b Full-aperture scheme of the STCM without partitioning, which can utilize the entire STCM aperture by using STC matrices. c Architecture of the ISAC system, in which a USRP is used for signal modulation and demodulation, and the STCM establishes a reliable communication link by sensing the direction of the incoming wave in real-time and configuring the coding matrices.
