英文摘要	Conference Name:OCEANS 2014 - Taipei. Conference Address: Taipei, Taiwan. Time:April 7, 2014 - April 10, 2014.; The multipath effect is the primary interference factor among the underwater communication systems. Underwater acoustic channels are characterized as time-variant dispersive channels. Multipath propagation results in spreading of the transmitted signal in time, which leads to serious Signal amplitude attenuation and inter symbol interference (ISI). Here we describes a signal processing approach identified as 'power cepstrum technique,' which has been found is efficient in recognizing wavelet arrival times and amplitudes, even in the present of noise. Thereby, a special signal, which has a short duration as well as a high power, is designed to detect the multipath effect of the channel.
