| Abstract: | Wediscussed some key techniques of m sequence used in spread sepectrum underwater acousticcommunication.A UAC channel coding schedule was presented.An equalizer algorithm wasdeveloped,and the envelope correlation decoding approach was also discussed.Simulationsshow that the equalizer is not only unsensitive to the estimated error of underwateracoustic channel,but also can detect signals in high noise environments. |
