Patent Searching and Data


Title:
AUDIO CHANNEL-BASED DIGITAL COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/161277
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of digital communications, and in particular, to an audio channel-based digital communication method and apparatus. The audio channel-based digital communication method comprises: step a: a sending end packs original data to be sent, and performs Manchester encoding on packed data packets, and sends the encoded data packets through an audio channel; and b: a receiving end samples the data packets sent by the sending end, and performs synchronous frame header detection and Manchester decoding processing on sampled data to obtain the original data. In the embodiments of the present application, Manchester encoding is employed at a sending end, and a correlation method is employed at a receiving end to perform Manchester decoding on received data, allowing for higher data transmission rates while meeting a need for higher data packet demodulation success rates, far exceeding data transmission rates in conventional audio communication methods, and making possible two-way communications between a master computer and a slave computer.
