Abstract
ABSTRACTThe paper presents the results of experimental researches of data transmission in water using Direct Sequence Spread Spectrum technique and the RAKE receiver. The signal with the QPSK modulation was spread by factor of 4, 8 or 16 chips. Researches were made to verify that spread spectrum technique can be used to underwater voice communications. Static studies were conducted in a small laboratory water tank and in a harbour. Propagation properties were evaluated based on the estimated impulse response of the hydroacoustic channel.
