Abstract
In this paper, we introduce the blind source separation(BSS) based signal processing idea, its mathematical model and three typical algorithms—ICA, SOBI and AMUSE. We also study the performance of the three algorithms using common waveform signals and the true signals. The experiments indicate that the algorithms are effective and feasible for suppressing interfering signals and extracting useful signals.
