A Comparison of Ungerboeck and Forney Models for Reduced-Complexity ISI Equalization
(2007) IEEE Global communications conference (Globecom), 2007 p.1431-1436- Abstract
- This paper investigates the performance of reduced-state
trellis-based intersymbol interference equalizers, which are based
on the so-called Ungerboeck and Forney observation models.
Although the two models are equivalent when an optimum equalizer
is employed, their performances differ significantly when using
reduced-complexity methods. It is demonstrated that practical
equalizers operating on the Forney model outperform those
operating on the Ungerboeck model for high signal-to-noise ratios
(SNRs), while the situation is reversed for low SNR levels. A
novel reduced-complexity equalization strategy that improves on
previous Ungerboeck-based... (More) - This paper investigates the performance of reduced-state
