WiFi-ZigBee reliable data transmission method based on symbol-level chip combination mode

The invention relates to the technical field of digital information transmission, and discloses a WiFi-ZigBee reliable data transmission method based on a symbol-level chip combination mode. The methdd comprises the following steps of: step 1, determining a twin symbol corresponding to a ZigBee symbol; step 2, according to the content to be sent, combining a corresponding symbol and a twin symbol thereof into a byte to obtain a combined signal; step 3, simulating a legal ZigBee frame by using an effective load of a WiFi frame; step 4, carrying out chip combination on the simulated symbol frame at a WiFi end; and step 5, sending out a symbol signal obtained by combining symbol-level chips through using a transmitter, and successfully identifying the signal sent by WiFi simulation by a ZigBee receiver and demodulating the identified signal. According to the WiFi-ZigBee reliable data transmission method, the receiving rate of a WiFi-ZigBee data packet is improved, the problem that the CTC efficiency from WiFi to
