COMPANION NYQUIST FILTER AND LINEAR EQUALIZER WITHIN A DATA TRANSMISSION SYSTEM

摘要

A transmission system (110) has a Nyquist filter (114) that operates upon a signal to shape signal spectrum. A first processed version of the signal is output from the Nyquist filter (114). A linear equalizer (112) of a system (110) operates upon the signal to pre-distort the signal in a manner that compensated for subsequent linear distortion. A second processed version of the signal is output from the linear equalizer (112). The linear equalizer (112) is located in parallel with the Nyquist filter (114). A combiner (118) combines the first and second processed versions of the signal.
