Abstract
Limited channel bandwidth introduces inter-symbol
interference (ISI) at both data and edge samples. In addition to the
ISI at data samples, ISI at the edge samples (edge ISI) increases
the bit error rate (BER) by degrading on the eye diagram and in-
creasing the jitter of the clock and data recovery (CDR). This work
proposes a forward FIR equalizer and a decision-feedback equal-
izer (DFE) that compensate for both data and edge samples. To
adapt both the data and edge equalizers, a modified LMS a
