Blind Two Real Signals Separation Method Based on Third Order Cumulants

This paper describes a blind two real signals separation method. Blind separation implies that there is no information about the signals except for received samples. This eliminates the presence of a systematic error in determining the stirring matrix and the restoration of the original signals. As a criterion for the separation of signals in this paper, the cumulants of the second and third orders of the output signals were reduced to zero. To test the performance of the method, mixing and separation model was created, and the efficiency of the method was tested at various power levels of the intrinsic noise in the receiving channels.
