COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/017111
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of computer applications. Provided are a communication method and apparatus. The method comprises: acquiring electrical signal information to be transmitted; determining, according to a preset vortex sound field production mode, transmitting information corresponding to the electrical signal information; converting, by means of a preset transmitting transducer array, the electrical signal information into a vortex sound field signal corresponding to the transmitting information; and transmitting the vortex sound field signal. The transmitting information of a vortex sound field signal corresponding to electrical signal information is determined by means of a preset vortex sound field production mode, and core sound field propagation of vortex sound communication is realized by producing or receiving any vortex sound field by means of a preset underwater transducer array, thereby reducing distortion, during encoding and decoding processes, of a signal that is transmitted underwater.
