Abstract :
In this paper, we propose a new blind separation criterion for second order cyclostationary sources with known and different cyclic frequencies. The method results from the spectral analysis; it is based on the use of the second order cyclostationary characteristics of the source signals. The theoretical results are presented and proved. The computer simulations show a good performance of the proposed method in comparison with Sobi, CycloSobi and Jade algorithms.
