Abstract: The blind equalization technique for MPSK signals is analysed and studied. A new blind equalization algorithm and the variable step-size blind equalization algorithm are presented. Computer simulations indicate that the new blind equalization algorithm and its improved form have a good convergence performance, so the communication systems can work continuously and do not require to be trained periodically. -
