Metasurface-based MIMO transceiver system

The invention provides a metasurface-based MIMO transceiver system, which is characterized by comprising a horn antenna, a transceiving isolation switch, a receiving link, a transmitting link, an intermediate frequency digital signal processing module, a digital controller and a metasurface, the horn antenna is connected with the transmit-receive isolation switch, the transmit-receive isolation switch is connected with the receiving link and the transmitting link, the receiving link and the transmitting link are connected with the intermediate frequency digital signal processing module, and the digital controller is connected with the intermediate frequency digital signal processing module and the metasurface. According to the invention, the metasurface and the single radio frequency transceiving link behind the single horn feed source antenna are utilized to realize the MIMO transceiving function at the same time, the limitation that the metasurface cannot process multi-user signals is overcome, and the maxi
