Underwater Acoustic Communication Algorithm Based on Turbo Code

Underwater acoustic communication is currently the only technological approach for long-distance information exchange underwater, and it is a key technology to ensure information transmission during the operation of underwater platforms. This article studies the underwater acoustic communication technology based on Turbo codes, aiming to solve the problem of high bit error rate caused by the complexity of underwater acoustic channels, improve the reliability and robustness of underwater communication systems, and have important theoretical significance and practical engineering value. Turbo coding has been widely used in wireless communication. Therefore, conducting research on underwater acoustic communication technology based on Turbo coding has important practical significance and broad application prospects. This paper proposes a design method for underwater acoustic communication system based on multi carrier OFDM-MFSK communication system and Turbo coding as source coding to address the high bit error rate problem in underwater acoustic communication. The simulation and experimental results show that this method significantly reduces the system error rate, and experiments were conducted on the canal, obtaining results with an error rate of less than.
