Abstract
A new method for blind source extraction of cyclostationary sources is presented. It is assumed that the cycle frequencies of the sources are known a priori and some of the sources have common cycle frequencies. Necessary and sufficient conditions are introduced and Jacobi method for diagonalization of complex matrices is used to find the estimations. The proposed algorithm is applied to simulated data, and effectiveness and performance of the algorithm are verified.
