The performance of the constant modulus algorithm can suffer because of the existence of local minima with large mean squared error (MSE). The paper presents a new method to obtain the optimum MSE over all delays using a second equaliser with a mixed constant modulus and crosscorrelation algorithm (CM–CCA). Proof of convergence is obtained for the noiseless case for a general symbol constellation. Simulations support the potential of the method even in noisy environments.
