摘要：
This paper introduces new source separation techniques exploiting the time frequency signatures of the source signals. The proposed approach relies on Time Frequency Distributions (TFD). Two TFD-based contrast functions are presented for non stationary sources. Iterative algorithms using the relative gradient technique are used to optimize the proposed contrast functions and perform the source separation.
