Abstract

"We present a novel adaptive algorithm for blind equalization. It is based on a tuner used in adaptive control that sets the second derivative of the parameter estimates and minimizes the cost function introduced by Godard. Based on simulation results we present a comparison with the Constant Modulus and the Shalvi-Weinstein algorithms. Both the convergence speed and the computational complexity of the proposed algorithm lie between those of the Constant Modulus and the Shalvi-Weinstein algorithms, thus presenting a more favorable compromise between convergence speed and computational complexity. Some preliminary results also suggest that the proposed algorithm presents a more robust behavior with respect to convergence to global minima."
