A novel baud-length memory FSE

The author presents a novel fractionally spaced equalizer (FSE) that spans a single symbol period. It is derived from the parametric estimates of a time-invariant or slowly time-varying baseband equivalent channel. The parametric channel estimates are assumed to be obtainable from a training sequence prior to data acquisition. The performance of the FSE depends to a large extent on how well the channel parameters can be estimated, and on the input signal-to-noise ratio (SNR) during training.<
