Abstract
Embodiments include apparatuses, methods, and systems including a decision feedback equalizer (DFE). The DFE includes a first summer circuit, a second summer circuit, a decision circuit, and a tap-delay line including a number of delay elements. The first summer circuit is to add together an analog signal and a first set of weighted feedback taps {h(j+1), . . . h(m)} of time delayed signals of a detected symbol to generate a first summand. The second summer circuit is to add together a second set of weighted feedback taps {h(k+1), h(n)} of time delayed signals of the detected symbol to generate a second summand. The decision circuit is to receive at least the first summand and the second summand, to generate the detected symbol based on a sum including the first summand and the second summand. Other embodiments may also be described and claimed.
