Abstract
Fractionally-spaced equalizers (FSE) are designed using the adaptive lattice algorithm. The design is compared with the lattice structure synchronous equalizer (SE). The effect of the sampler phase on the mean square error (MSE) is investigated. It is shown that the FSE is not affected by the sampler phase. Improved performance of the FSE over the SE design as applied to severe amplitude distortion channel is obtained when its time span is made equal to that of the synchronous equalizer.
