COHERENT WATER ACOUSTIC COMMUNICATION SYSTEM AND SIGNAL PROCESSING METHOD WITH A HIGH PROCESSING RATE AND LOW ERROR PROBABILITY

摘要

The present invention relates to a kind of water acoustic coherentlycommunication system and signal processing method having high code rate, lowprobability of error The present invent relate to a kind of water acousticcoherently communication system and signal processing method for transferringinstruction, data and picture underwater at high code rate, low probability oferror. The system include mainframe and consumer machine, in which themainframe fitting on mother ship or main control underwater vehicles A, whichinclude electronic extension set, transmission energy converter and receiveline array which vertical hung in water and made up of more than twohydrophones. The consumer machine fitting on underwater vehicle B, whichinclude electronic extension and send-receive energy transducer. The inventivewater acoustic coherently communication signal processing method adoptingspace diversity technology, self-optimization self-adaptive decision feedbackequalizer and self-optimization self-adaptive phase tracker team workingsignal processing method, overcome influence of channel and vehicles moving,so as to the received signal is very closed to the transmitted signal, and bitprobability of error lower.
