Abstract

Recently, a novel method for blind channel equalization based on the truncation of the covariance matrix has been proposed. Despite having interesting properties, more specifically its low complexity through adaptive implementation and its robustness to channel over-modeling, this method, is based on zero delay equalization thus yielding non satisfactory results in case the first channel coefficient is of low power. In this paper, we propose to generalize this method to nonzero delay equalization. We show that the proposed method not only inherits the same interesting properties of the original one, but also improves considerably its performance and its sensitivity to the value of the first channel coefficient.
