High performance architectures for adaptive equalizers using distributed arithmetic

Abstract

In communications adaptive decision feedback equalizers ADFEs are an effective means of countering the intersymbol interference ISI introduced by the channel and also to keep track on the changes in the channel characteristics However high speed applications demand for a large number of taps in the feed forward filter FFF and feedback filter FBF of ADFE and hence the implementation and real time operation of such an equalizer becomes difficult due to increased complexity and very smal
