Abstract :
This paper deals with blind separation of convolutive mixtures of continuous phase modulated (CPM) sources. The main difficulty lies in the fact that CPM sources are non linear (and hence non i.i.d.) sources. We consider a particular contrast function, which is proved to be closely related to the constant modulus (CM) criterion. The connection between the two criteria allows us to prove the validity of the contrast. Using recent results about CPM equalization, we are able to characterize the scalar filtering ambiguity. Simulations follow and show the efficiency of the method.
