In this paper, the blind equalization problem in presence of bounded noise with different modulations (QAM, PSK and ASK) is addressed. A first blind equalization algorithm is reminded, then an extension is proposed. Few synthesis parameters have to be fixed by the user in the proposed approach. In order to illustrate the efficiency of the proposed algorithm, we compare with another well known existing technique. Simulation results prove the good performance of the proposed algorithm.
