Adaptive equalisation in oversampled subbands

Adaptive equalisation in oversampled subbands
Adaptive equalisation in oversampled subbands
The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long filters, which can have slow convergence for LMS-type adaptive algorithms. This paper presents a novel oversampled subband approach to adaptive equalization, which can both significantly reduce computational complexity, and improve convergence speed.

Abstract

The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long filters, which can have slow convergence for LMS-type adaptive algorithms. This paper presents a novel oversampled subband approach to adaptive equalization, which can both significantly reduce computational complexity, and improve convergence speed.
