Aiming at the analysis of the underwater acoustic channel such as complex and changeable, strong multi-path and large fluctuation interference, this article establishes an underwater acoustic communication system with polar codes as the channel coding scheme to improve the reliability of underwater acoustic data transmission. A Monte Carlo construction is proposed as a construction scheme of polar codes, and simulation results are obtained in three typical underwater acoustic channels. The results show that the construction scheme of polar codes proposed in this article is feasible and effective in these three channels. Compared with the Low Density Parity Check Code (LDPC) with similar code length, the comprehensive performance of the polar codes is better at the same Eb/N0. Relatively speaking, when the Eb/N0 is improved, the bit error ratio (BER) curve drops faster, which means that it can provide a higher coding gain. This article proves that the polar codes can obviously improve the performance of the underwater acoustic communication system, which will have a good application prospect in the complicated underwater acoustic channel.
