Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for far-field acoustic wave communication based on a microphone array. Background technique [0002] As the use of acoustic wave communication becomes more and more extensive, the hardware support of acoustic wave communication is very extensive and has extremely high versatility. Since the transmission medium of acoustic wave communication is air, the volume of the device, the distance of communication, and the level of environmental noise will all become the influencing factors in the use of acoustic wave communication, which also limits the application of acoustic wave communication. [0003] At present, acoustic wave communication is mostly used in the use scenarios of ultra-short-range audio signal transmission, which can only transmit control information of low rate and small amount of data, and the coding efficiency is low. In ad...
