Abstract
Official abstract text for this publication.
An equalizer and an equalizing method for equalizing a received signal, where the received signal includes at least one primary interference and a plurality of secondary interferences. The Viterbi equalizer includes a filter module for filtering out the secondary interferences from the received signal to generate a filtered signal, a serial to parallel converter, coupled to the filter module, for generating a plurality of sequences according to the filtered signal, and a Viterbi equalizing module, coupled to the serial to parallel converter, for respectively equalizing the plurality of sequences to generate a plurality of equalized sequences. The architecture of the Viterbi equalizing module is greatly simplified thereby reducing the calculation activity of the Viterbi equalizer as well as maintaining its efficiency.
First claim
Opening claim text (preview).
What is claimed is: 1. An equalizer comprising: a feed forward filter configured to receive a signal and generate a first filtered signal; and a filter module configured to receive the first filtered signal and generate a second filtered signal, the filter module comprising: a decision feedback equalizer comprising a feedback loop includes a first subtractor configured to receive the first filtered signal, a decision unit coupled to the first subtractor and configured to output…
