This paper discusses the Turbo coding scheme to improve the system reliability in the remote acoustic communication system. The performance of the Turbo coding scheme in a given underwater acoustic channel and joint modulation mode is simulated. The factors affecting the error correction performance are discussed Analysis, and the upper bound of the bit error rate under the condition of underwater acoustic channel is deduced. It shows that Turbo coding scheme can greatly improve the reliability of remote acoustic communication system.
