“…Polar code is the first method that theoretically reaches the Shannon limitation, and has lower coding complexity than low-density parity-check (LDPC) and Turbo codes. Nevertheless, there are few works studying on polar codes for the UWA channels [2][3][4]. Monte Carlo [2,3] and Bhattacharyya boundary [3,4] approaches are often used to construct polar codes.…”

To improve the performance of underwater acoustic communications, this letter proposes a polar coding scheme with adaptive channel equalization, which can reduce the amount of feedback information. Furthermore, a hybrid automatic repeat request (HARQ) mechanism is provided to mitigate the impact of estimation errors. Simulation results show that the proposed scheme outperforms the turbo equalization in bit error rate. Computational complexity analysis is also provided for comparison.

“…Nevertheless, there are few works studying on polar codes for the UWA channels [2][3][4]. Monte Carlo [2,3] and Bhattacharyya boundary [3,4] approaches are often used to construct polar codes. However, the former is based on statistical performances, while the latter requires the feedback of channel gains and noise variance.…”
