A decision feedback equalizer finite impulse response (DFE FIR) filter for
cancelling inter-symbol interference within a signal transmitted through
a communication channel. The DFE FIR filter includes a feed-forward
equalization path to receive the signal transmitted through the
communication channel and generate a first partially equalized signal
from the signal based on a plurality of coefficients associated with the
feed-forward equalization path; a feedback equalization path to generate
a second partially equalized signal that corrects for the inter-symbol
interference within the signal based on an output of the DFE FIR filter;
a summer to combine the first partially equalized signal with the second
partially equalized signal; and a signal amplifier to receive the
combined signal from the summer and generate the output of the DFE FIR
filter.
