Abstract
The present invention discloses a visible light signal transmitting and receiving processing method, a transmitting terminal, a receiving terminal, and a system. The method includes: performing, by a transmitting terminal, an operation between data to be sent and a pseudocode signal of the transmitting terminal to output a scrambled code signal; combining, by the transmitting terminal, the scrambled code signal with a light guide signal to obtain a signal to be sent, where the light guide signal includes identity information of the transmitting terminal; and transmitting, by the transmitting terminal, the signal to be sent in light form. The present invention solves a problem that an encryption method for visible light communication in a related art is applicable to only one transmitting terminal, and thereby multiple transmitting terminals can be supported.
