Abstract
A key component of a 2 dimensional read channel architecture is the 2D equalizer. For 2D PRML channels, the complexity of the equalizer needed is high and presents a challenge for practical implementation. A transform domain 2D equalizer for use in multitrack 2D storage systems is presented. The architecture offers a significant reduction in complexity for short length transforms, when compared to an equivalent time-domain equalizer.
