In order to remove these coherentnoise, the method of KL transform are discussed and implemented in this paper?
探讨了采用KL变换消除这些水平相干噪声的方法，并给出了具体的实现步骤。

And then, establish the adaptive thresholding algorithm. Thus, we get a new adaptive threshold denoising method fit for coherentnoise.
并在此基础上确定了自适应阈值计算方法，建立了新的阈值去噪法，可用于去除相干噪声。

The coherentnoise of single mode fiber is restrained by the amplification effect of anti Stokes Raman backscattering, and the signal noise ratio of sensor system is improved.
