Patent ID: 10985952

Abstract:
A method of a data transmission apparatus applied in high-speed wired network includes: performing analog-to-digital conversion operation upon a time-domain analog training data signal transmitted from a link partner device to generate a time-domain digital training data signal; converting the time-domain digital training data signal into a frequency-domain training data signal; performing a frequency-domain feed-forward equalization (FFE) operation upon the frequency-domain training data signal to generate a frequency-domain FFE resultant signal; converting the frequency-domain FFE resultant signal into a time-domain FFE resultant signal; generating a difference resultant signal according to the time-domain FFE resultant signal and a feed-back equalization (FBE) resultant signal; receiving the difference resultant signal to generate a slicer resultant signal; and using the FBE operation to generate the FBE resultant signal according to the slicer resultant signal.
