Abstract:〖WT5BZ〗According to propagation mechanism of voice signal and characterization capabilities of Bessel function expansion coefficient,this paper presents a method of modeling voice signal.The method bases on Bessel function expansion,and it makes choosing reference signal easily in voice Independent Component Analysis with Reference (ICA with Reference,ICA-R) algorithm.The reference signal in ICA-R is constructed by coefficient,and voice signals are extracted in this way.Results of simulation experiment indicate that this method can extract expected signal,hid and recover voice signals effectively.
