摘要：
A scheme of demodulation based on wavelet analysis for underwater acoustic signal is presented in this paper. The demodulation applied on the signals modulated by FSK modulation or PSK modulation is analyzed in theory. The idea is to use wavelet transform to locate the jump points when phase changes or frequency changes. This method has a better performance for PSK signals than for PSK signals. The reliability and performance of the proposed method are verified by Matlab simulation.
