| Abstract: | According to the deficiency of slow convergence and phase rotation of CMA, several good blind equalization algorithms based on Constant Modulus Criterion, including variable step-size CMA, fractional-space CMAandmulti-modulus algorithm are analyzed and simulated. The advantage and disadvantage of all the modified algorithms are also described and explained. Constellation figures and MSE curves are obtained after equalization. |
