Abstract:
It discloses an acoustic channel-based data communications method which performs channel coding on an original data signal using a CRC coding method and a BCH coding method to obtain a coded sequence; modulates the coded sequence using a preset audio sequence symbol set via a symbol mapping method to obtain a digital audio signal; selects a channel frequency band according to characteristics of a transmitting equipment and interference between frequency bands; and converts the digital audio signal into an analog audio signal through a digital-to-analog converter and transmits the signal to a channel for transmission according to the selected channel frequency band.

Claim (Index 1):
An acoustic channel-based data communications method, comprising:\n receiving an analog audio signal transmitted in a channel and converting the analog audio signal into a digital audio signal through an analog-to-digital converter; eliminating strong interference channel frequency band data from the digital audio signal by calculating the cross-correlation between the digital audio signal having a frequency within the range of each channel frequency band and an original sample signal; capturing a synchronization symbol by calculating the cross-correlation between a synchronization symbol sample and the digital audio signal with strong interference channel frequency band data eliminated, and performing symbol inverse mapping, thus completing signal demodulation and obtaining a digital sequence; and performing channel decoding on the digital sequence using a CRC decoding method and a BCH decoding method to obtain the original data signal.
