| Abstract: | In this communication, we propose a new method to blindly identify the mixing matrix of a possibly under-determined mixture of sources when input signals are cyclo-stationary. It is based on the use of a linear operator applied on the observations correlation matrix. Exploiting the properties of the above transformed matrix, we can estimate a set of cyclic frequencies leading to the estimations of the different columns of the mixing matrix. Finally using a classification procedure, the mixing matrix is then estimated. | ||
