Abstract: The In work it is shown that the hydroacoustic channels of impulse noise or short-term interruptions for improving the quality of data transmission can be applied different variants of convolutional and cyclic codes. Convolutional codes at a rate of R ≤ 3/4 in conjunction with broadband signals (BBS) or convolutional codes R ≤ 2/3 with code interleaving algorithm can reduce the probability of an error at the output channel for the known error statistics. Taking into account the energy gains from the computational complexity of encoding and interleaving of code is more favorable option “code + BBS” to 4÷5 interlaces. Given the multi-bit optimal filter BBS, its implementation is always more difficult than implementing a threshold decoder trellis
