Photon-assisted ultra wide band millimeter wave multichannel receiver

The invention provides a photon-assisted ultra wide band millimeter wave multichannel receiver, which performs channelization division on ultra wide band millimeter wave multichannel signals by adopting radio frequency-free local oscillator microwave photon frequency conversion, high-frequency stable multi-channel channelization optical local oscillator generation and multi-channel parallel coherent detection technologies, and improves the receiving efficiency under the constraint of a low-cost analog-to-digital converter. Through parallel channel analog-to-digital conversion and receiving processing, the function of receiving ultra-wideband millimeter wave signals in a high-sensitivity parallel narrow-band mode is achieved, and millimeter wave wireless communication large-capacity and long-distance transmission is supported. The problems of ultra-wideband signal receiving, analog-to-digital conversion and processing in millimeter wave wireless communication are solved, large-capacity and long-distance transm
