Document Type and Number:
WIPO Patent Application WO/2015/074617
Kind Code:
A1
Abstract:
The present invention provides a data transmission method and apparatus, a mobile terminal, and an acoustic communications system. The method comprises: a first terminal device performing coding, modulation and frequency mixing of to-be-transmitted data according to a received data transmission operation instruction, so as to generate a first frequency-mixed electric signal; the first terminal device converting the first frequency-mixed electric signal into an acoustic signal and sending the acoustic signal to a second terminal device; and the second terminal device converting the acoustic signal into a second frequency-mixed electric signal, and performing frequency division, demodulation and decoding of the second frequency-mixed electric signal, so as to obtain the data sent by the first terminal device.
