Research on the Application of Polar Codes in Underwater Acoustic Communication
Aiming at the characteristics of the underwater acoustic channel such as complex and changeable
strong multi-path and large fluctuation interference
this paper establishes an underwater acoustic communication system with polar code as the channel coding scheme to improve the reliability of underwater acoustic data transmission. Aiming at the channel with invariable sound velocity gradient(ISVG)
negative sound velocity gradient(NSVG) and positive sound velocity gradient(PSVG)
a Monte Carlo construction is proposed as a construction scheme of polar code. Performance simulations on each channel show that the polar code construction scheme proposed in this paper is feasible and effective under three channels. Compared with the low density parity check code(LDPC) with similar code length
the comprehensive performance of the polar code is better under the same signal-to-noise ratio(SNR). Relatively speaking
when the SNR of the polarization code is improved
its bit error rate curve drops faster
which means that it can obtain a higher coding gain. The simulation results improve the performance of the underwater acoustic communication system
and show a good application prospect in the complicated underwater acoustic channel.
