A Comparison of Ungerboeck and Forney Models for Reduced-Complexity ISI Equalization

Rusek, Fredrik LU ; Loncar, Maja LU and Prlja, Adnan LU (2007) IEEE Global communications conference (Globecom), 2007 In IEEE Global Telecommunications Conference, 2007. GLOBECOM '07. 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)
