Abstract

A new equalization method for Blu-ray (BR) recording channels is proposed. The proposed equalizer incorporates the Gaussian sum approximation (GSA) into a Kalman filtering framework to mitigate intersymbol interference in BR recording systems. The proposed equalizer consists of a bank of linear equalizers using the Kalman filtering algorithm and its output is obtained by combining the outputs of linear equalizers through the GSA. The proposed equalizer shows a better performance than the conventional equalizers and a similar performance with the only equalization technique to the partial response maximum likelihood methods in terms of bit-error-rate.
