Abstract: A massive multiple-input multiple-output channel emulation method and a device based on optical matrix switching are provided. The method is realized based on a massive multiple-input multiple-output channel emulation system, which includes a plurality of channel preprocessing subsystems, an optical switching subsystem, a plurality of channel characteristic emulation subsystems, a self-checking and self-correcting subsystem, a mathematical simulation and monitoring subsystem and a time-frequency synthesis and distribution subsystem. All the subsystems are interconnected by various optical fiber connections, which are used to transmit high-speed data signals, communication information, control instructions, frequency, pulse and time signals, and have the centralized-distributed layout ability of various devices in the system based on long-distance transmission of optical fiber signals, and have the massive parallel expansion ability of the number of system signal input and output links.
