Optimum delay and mean square error using CMA
D.J. Brooks, Sangarapillai Lambotharan, Jonathon A. Chambers · 2002
The performance of the constant modulus algorithm can suffer because of the existence of local minima with large mean squared error (MSE). This paper presents a new way of obtaining the optimum MSE over all delays using a second equalizer under a mixed constant modulus and cross correlation algorithm (CM-CCA). Proof of convergence is obtained for the noiseless case. Simulations demonstrate the potential of the method.
