Background: Because of signal attenuation, multipath fading, and Doppler phenomena, the underwater environment provides unique obstacles for communication channels. Traditional approaches often need to address these issues appropriately. Objective: This article aims to investigate the possibility of combining polar codes with OFDM (Orthogonal Frequency Division Multiplexing) methods to improve the performance and reliability of underwater communication systems. Methods: The suggested models combine polar codes' capacity-achieving and error-correcting qualities with the robustness of OFDM against impairments such as impulsive noise. Key parameters such as bit error rate (BER), signal-to-noise ratio (SNR), and channel capacity were examined to assess the model's efficacy. Results: Compared to traditional communication systems, simulations and tests show a 30% reduction in BER, a 20% increase in SNR, and a 25% increase in channel capacity. These measures highlight the tremendous advances in underwater channel performance that polar code-OFDM models provide. Conclusion: The combination of polar codes with OFDM is a viable method for improving the capabilities of underwater communication systems. The significant gains in performance indicators suggest potential applications in underwater sensor networks, oceanographic data transmission, underwater robotics, and deep-sea research. This study makes an important contribution to the advancement and dependability of underwater communication systems.
