Blind source separation of a mixture of communication sources emitting at various baud-rates

A blind source separation problem in a cyclostationary context is addressed. The mixture stems from several telecommunication signals, the baud-rates of which are possible different. Cost functions are introduced, the optimization of which achieves the equalization for a user (i.e. estimation of the baud-rate and the sequence of symbols). The method is iterated by implementing a deflation. The theoretical results are validated by simulations
