Abstract
A serialiser/deserialiser (SERDES) receiver 11 comprises a feed forward equaliser (FFE) 4 and a decision feedback equaliser (DFE) 5 acting as a data slicer. The FFE makes an estimate of a future sample by slicing the future sample with respect to a predetermined slicing level and corrects a current sample for the effect of the future sample before it is sliced by the DFE. The FFE subtracts at least one quantising level from the current sample if the future bit is rendered as a 1 or adds at least one quantising level if the future bit is rendered as a 0. The receiver is arranged such that the subtraction and addition are performed only if the bit values of the current and future samples as rendered by the FFE are different. The invention prevents the FFE from applying a correction that is adverse to noise margin and bit error rate by moving the current sample value closer to the data slicing level of the data slicer.
