Abstract
A receiver of digital signal pulses, operating with a sampling period T, comprises an equalizer which includes at least one feedback loop from the output of a decision unit for subtracting from an incoming signal pulse a value corresponding to the magnitude of a tail or postcursor of a preceding signal pulse. The signal pulse thus purged of postcursor interference is delayed by one or more sampling periods T for algebraic combination with one or more fed-forward compensating signals each representing the estimated value of an interfering precursor sample, these compensating signals being derived from the outputs of respective decision units with the aid of filters.
