Abstract
Tap spacings in a tapped delay line equalizer are optimized. We derive a set of nonlinear equations for the optimum tap spacings and tap weights for the decision feedback equalizer. A recursive numerical technique is used to obtain the optimum settings. The nonuniformly spaced tapped delay line equalizer with the optimized tap spacings outperforms the conventional uniformly spaced equalizer with the same number of taps
