| Abstract(in English) | A complex random signal has an isotropic probability distribution, which serves as a model of altenatecurrent noise, radio wave signal or a narrowband signal.The present paper deals with the blind separation of the mixtures of such independent complex signals, by introducing conplex Hermite moments based on the complex Hermite polynomials and their tensorial properties under unitary transformation and by maximizing a cost function in terms of their moments.We simulate 2D complex signal separation based on 2D unitary matrices SU(2), using complex random numbers and narrowbanded speech signals.The same process is applied to separating independent narrowband signals with time differences in signal mixing. |
