FIELD: hydro acoustics.
SUBSTANCE: invention relates to hydroacoustics and can be used in systems for underwater digital communication in conditions of high level of interference from propagation multipath of acoustic signal; essence: the protection from interferences of multibeam and reverberation is achieved by using synchronously tunable frequencies grid synthesizers in the transmitter and the receiver for transmission and reception of each separate bit code sequence in a combination with control clock generators, carrying out byte and bit data synchronization.
EFFECT: high noise immunity to in-symbolic and inter-symbolic interference of acoustic beams at high speed of data transfer and increased remotability of the communication channel.
