Abstract (en)
[origin: GB2336277A] A decision feedback equaliser 50 is preloaded with filter coefficients for training purposes. A data signal is received which includes a training sequence. A sample value of the training sequence are correlated 34 with a stored equivalent training sequence and the peak correlation value is determined. A first set of correlation values is preloaded into a feedforward portion 42 of the DFE for use as initial feedforward filter coefficients before training and the outputs of a feedforward filter are used as initial feedback filter coefficients in a feedback portion 48 of the DFE.
