【Abstract】 A new blind equalization algorithm based on diagonal recurrent neural networks(DRNN) is proposed.The algorithm has the advantages of simple structure and less computational requirement.Combined with the conventional constant modulus algorithm(CMA),a new cost function is proposed,then the steepest descent method is used in DRNN training.Simulation results show that this algorithm could converge quickly and had less bit error ratio.更多还原
