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 7):
The acoustic channel-based data communication method according to  claim 5 , wherein the modulating the coded sequence using a preset audio sequence symbol set via a symbol mapping method to obtain a digital audio signal specifically comprises:\n selecting a sequence symbol as a synchronization symbol for a data frame of the digital audio signal; selecting 2 n+1  sequence symbols from the preset audio sequence symbol set and classifying the 2 n+1  sequence symbols into odd mapping symbols and even mapping symbols, wherein the number of the odd mapping symbols is equal to that of the even mapping symbols, and n=1, 2, 3 . . . ; dividing the coded sequence into a plurality of coded sequence groups, each coded sequence group comprising n bit data; and mapping the odd coded sequence group into a sequence symbol in the odd mapping symbol according to a preset mapping relation, and mapping the even coded sequence group into a sequence symbol in the even mapping symbol according to the preset mapping relation, thus mapping the coded sequences into a plurality of digital audio symbols; wherein the synchronization symbol and the plurality of digital audio symbols form a data frame of the digital audio signal.
