A New Variable Step-size Constant Modulus Blind Equalization Algorithm

Abstract

This paper derives a new variable step-size Constant Modulus Blind Equalization Algorithm, which uses the cross-correlation coefficient estimation between the input signal and the error signal to control the step-size of CMA. The new algorithm resolves the contradiction between the convergence rate and the convergence precise with the fixed step-size. Computer simulations show that the new algorithm has better convergence performance than conventional CMA.
