description The present invention discloses a passive WiFi scatter communication method and system based on an MCU microprocessor which are implemented by employing an MCU, a radio frequency electronic switch device, an antenna and an antenna impedance matching circuit. The method and the system achieve the processes such as WiFi data frame formation, scrambling, difference code conversion, spread spectrum and digital virtual modulation on the MCU; a digital virtual DBPSK modulation method is provided to achieve the digital virtual DBPSK modulation through compiling of the MCU program; the general serialcommunication interface of the MCU is employed to output chip bits with high rate/modulation sequence bits to directly drive the radio frequency electronic switch device to switch the absorption/reflection state of the antenna; and in order to further reduce the MCU dominant frequency and further reduce the power consumption, a modulation method of the MCU + a logic circuit is provided to allow more general single chip mi
