Error event characterization and coding for the equalized Lorentzian channel

Abstract

Coding methods to enhance the performance of sequence estimators for an intersymbol interference (ISI) channel are presented. The ISI channel considered is modeled with a Lorentzian step response, and equalized to a finite-duration, discrete impulse response. The coding follows from a characterization of the dominant error events for a suboptimal sequence estimator which uses a Euclidean distance metric for detection of a signal in colored noise.
