Abstract
The present invention relates to a wireless communication system and a method thereof. The wireless communication system comprises a signal encoding module for encoding a preset high-frequency audio signal frequency according to a preset 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 decoding the main frequency into a preset code according to the code in the library; and an output module for outputting the decoded code. The wireless communication system and the method of the present invention do not need hardware supports, thereby reducing the cost.
