| Abstract: | Constant modulus adaptive blind equalization technique is studied and the direction of improving and designing this kind of equalization is summarized. A variable step-size multi-modulus blind equalization algorithm is proposed based on the cost function of constant modulus algorithm. Computer simulations show that the algorithm has fast convergence and small steady-state error, and thus it is of practical importance. |
