Abstract

To further improve the performance of extraction of harmonic signal from chaotic background, an effective data segment based separation method for single channel signal was proposed. The single channel signal is mixed by chaotic signal and harmonic signal, and empirical mode decomposition (EMD) can transform the single channel signal into positive definite separation problem by intrinsic mode function (IMF). However, EMD has the endpoint effect problem which results in the signal distortion on boundary. Hereby we use the effective data segment of IMF to carry on the independent component analysis (ICA) processing to obtain the separation matrix, which can avoid the distortion signal effect on the result. Computer simulation verified that the proposed method is high availability.
