Abstract :
The paper presents a novel technique for underwater acoustic voice communications. The speech signal is compressed prior to transmission by using linear predictive coding and transmission of appropriate speech parameters is achieved by digital pulse position modulation. The main emphasis is on the reception of the multipath-dominant signal and on the demodulation process
