In order to improve measurement accuracy in the polarization mode dispersion(PMD)measurement system by the fixed analyzer method,the noise in the link should be eliminated.Here,apolarization mode dispersion measurement scheme based on empirical mode decomposition(EMD)adaptive filtering to mitigate noise is proposed.According to signal spectral characteristics,it is decomposed into a finite number of intrinsic mode functions(IMFs),which are arranged by frequency from large to small.The consecutive mean squar...
