英文摘要	For channel estimation of the communication system, SNR (Signal to Noise Ratio) estimation is a very important parameter. In this paper, we combine the classical Rayleigh and Rician channel with additive white Gaussian noise to simulate the underwater acoustic channel statistical models. Then we apply the SNR estimation method M2M4 (Second order and Fourth order Moment method) for LFM system in underwater acoustic channel. Furthermore, according to the characteristics of both LFM system and channel models, we put forward the improvement of M2M4 based on FRFT (Fractional Fourier Transform) to increase the algorithm performance for underwater acoustic Rayleigh Gaussian channel, Rician Gaussian channel and Ray Tracking channel. ? 2013 by Binary Information Press.
