Mixed Sound Signal Separation Based on Independent Component Analysis

WANG Xiao-wei,LIN Suo (No.502 Staff Room,Second Artillery Engineering College,Xi'an 710025,China)  
The application of fix-point algorithm based on the independent component analysis(ICA)in speech signal includes firstly,record music in a peaceful environment and saving the wave document as Signal1.wav;and secondly,records a talk of a person under the same environment.Experimenter counts some numbers by steady language,and records the sample in the frequency of 16 kHz as Signal2.wav.Estimated signals can be acquired by using the method and approach as:Open and take a sample,randomly create a mixture matrix,and mix two documents.
