A new BSS method based on independent sub-band function components (ISBF) and wavelet to separate single-channel mixture signal in noise was studied. Through obtaining sub-band functions with independent component characteristic in the time domain, 6-20 sub-band function by ICA were employed as the preparation knowledge for the blind source separation (BSS). By combining the independent sub-band function components (ISBF) into the single-channel mixture signal, a separation modeling of single-channel mixture signal was built based on ISBF. And the separation mathematics model of the single-channel signal in noise is investigated. The wavelet transform was used to eliminate the noise as well. Two simulation samples performed to verify the availability of the proposed methods. The results show that the methods played good role in one sensor source BSS, and had a capability to extract the sound signal feature.
