METHOD FOR HIGH-SPEED TRANSMISSION AND RECEPTION OF INFORMATION IN HYDROACOUSTIC MULTIBEAM COMMUNICATION CHANNEL Russian patent published in 2023 - IPC H04B7/02 H04L17/02 

FIELD: information transmission.

SUBSTANCE: invention is intended for encoding/decoding the reception and transmission of information in the aquatic environment of the deep and shallow seas. The initial impulse response of the channel is obtained from the received reference pulses, which is then refined by estimating it at each processing step directly from information impulses when performing correlation operations of information impulses used to estimate the purified discrete impulse response of the channel, and decorrelation information pulses used to estimate the full continuous impulse response of the channel, with their subsequent transformation, accumulation of estimates of the discrete and continuous impulse response of the channel and implementation of coordinated filtering, thus forming feedback with the decision making function connected to the decoder, the estimates of the cleared discrete and complete continuous pulse characteristics of the communication channel for all information and reference pulses are carried out simultaneously, and the signal modulation is used in form of time-frequency modulation.

EFFECT: increase of communication speed and improvement of quality of information reception in a hydroacoustic multi-beam communication channel.
