Claim:
1. A wireless communication system, comprising: a signal encoding module for encoding a preset high-frequency audio signal frequency according to a present encoding rule, and creating an encoding library for storing the code, a signal sampling module for sampling a high-frequency audio signal produced by a high-frequency audio signal generating device; a signal transformation module for performing Fourier transformation on the sampled audio signal firstly to transform the audio signal into frequencies, acquiring a main frequency from the transformed frequencies, and storing the acquired main frequency; a signal decoding module for receiving the code from the encoding library and then decoding the acquired main frequency into a preset code according to the code in the library; and an output module for outputting the decoded code; wherein the encoding rule refers to using a preset high-frequency audio signal frequency to represent a value of each bit in a binary system, and inserting an XOR parity bit between every two bits of the binary system, wherein a value of each XOR parity bit is also represented by the preset high-frequency audio signal frequency.
