Coefficient error robust feed forward equalizer

摘要

The present invention relates to a coefficient error robust feed forward equalizer and, more specifically, to a feed forward equalizing transmitter for baseband wired communication for preventing the influence of a coefficient error generated by the variation of nano-elements. The coefficient error robust feed forward equalizer according to one embodiment of the present invention comprises: a receiving terminal (130) for receiving input data (x) according to an integer time index (n), N number of delay units (D) connected with the input terminal (130) in series, a first calculator (110) for summing up tap signals outputted respectively from the N number of delay units (D); and a data change detection filter (120) for outputting a data transition value (b) on the basis of the change in the input data (x).

1. A coefficient error robust feed forward equalizing transmitter comprising:
an input terminal (130) configured to receive input data (x) according to an integer time index (n); a plurality of delay units (D) connected in series with the input terminal (130), wherein said delay units are configured to output tap signals; a data change detection filter (120) disposed between two adjacent delay units among the plurality of delay units, connected in series with the two adjacent delay units, and configured to output a data transition value based on a change in the input data (x); and a first calculator (110) configured to sum the tap signals, wherein the delay units connected behind the data change detection filter output the tap signals based on the data transition value output by the data change detection filter (120).
