The research domain of underwater communication has garnered much interest among researchers exploring underwater activities. The underwater environment differs from the terrestrial setting. Some of the main challenges in underwater communication are limited bandwidth, low data rate, propagation delay, and high bit error rate (BER). As such, this study assessed the underwater acoustic (UWA) aspect and explored the expression of error performance based on t‐distribution noise. Filter orthogonal frequency‐division multiplexing refers to a new waveform candidate that has been adopted in UWA, along with turbo and polar codes. The empirical outcomes demonstrated that the noise did not adhere to Gaussian distribution, whereas the simulation results revealed that the filter applied in orthogonal frequency‐division multiplexing could significantly suppress out‐of‐band emission. Additionally, the performance of the turbo code was superior to that of the polar code by 2 dB at BER 10⁻³.

具有高斯分布噪声的水声通信中基于极化码的滤波器正交频分复用方案

水下通信的研究领域引起了探索水下活动的研究人员的极大兴趣。水下环境与陆地环境不同。水下通信中的一些主要挑战是带宽受限，数据速率低，传播延迟和误码率（BER）高。因此，本研究评估了水下声学（UWA）方面，并探讨了基于t分布噪声。滤波器正交频分复用是指UWA中已采用的新波形候选，以及Turbo和极地码。实验结果表明，噪声不符合高斯分布，而仿真结果表明，正交频分复用中使用的滤波器可以显着抑制带外发射。另外，在BER 10 ^-3处，turbo码的性能比极地码的性能高2 dB 。
