MIMO optical wireless communication system based on image acquisition and communication processing method thereof

The invention discloses an MIMO (Multiple Input Multiple Output) optical wireless communication system based on image acquisition and a communication processing method thereof. The MIMO optical wireless communication system comprises a signal receiving unit, a pulse modulation unit, a signal processing unit and a multipath anti-interference unit, wherein the signal receiving unit manages and receives wireless communication signals, and the process from signal receiving to signal transmitting is completed; the pulse modulation unit adjusts the received signals through three-way transmission, adjusts the output signals through the change of the input signals, and completes the pulse width modulation; the signal processing unit performs terminal modulation processing on the modulated signal through combination of pre-operation and post-operation to ensure integrity of the output signal; the multipath anti-interference unit prevents intervention of external interference signals, and guarantees the anti-interferen
