Abstract :
The paper gives a parameter estimation and blind equalization algorithm for a nonminimum phase channel. The channel model is assumed to be moving average (MA) based. To identify the channel parameters, the fourth order cumulant fitting approach is adopted. In addition, the initial values of the iteration are determined by a special method to obtain the global solution
