Operation of a decision feedback equalizer is enhanced by measuring the intersymbol
interference precursor effect on each symbol decision output and utilizing that measurement …

An improved decision feedback equalizer, which re moves intersymbol interference from
pulse transmis sions having a desired period, includes an arithmetic circuit (9) for extracting …

A center tap of a transversal filter, which forms part of a forward equalizer, is shifted by at
least one symbol interval. An error signal is generated using a decision output and tap …

An equalization circuit is disclosed that enables high data rate transmission over high loss
communications channels. Also disclosed is a set of functional blocks and update criteria …

The feedforward filter section of a decision feedback equalizer is modified to include one or
more postcursor taps, that are sequentially weighted at decreasing binary fractions of the …

(57) ABSTRACT A method and apparatus for a decision feedback equalizer wherein a
correction term is used to compensate for slicer errors, thus avoiding error propagation. Filter …

Equalizers such as adaptive decision feedback equalizers having a plurality of taps are
widely used in digital com munication receivers in order to provide correction for multipath …

Conventional adaptive equalizers often use the “sign/sign” algorithm as a low complexity
means to adjust their tap weight coefficients by driving the correlation between its single-bit …
