A Novel Phenomenological Model of Equalization-enhanced Phase Noise

TL;DR

This paper introduces a phenomenological model for equalization-enhanced phase noise, describing it as a time-varying, frequency-dependent phase error that can be mitigated using a specific filter.

Contribution

It presents a new model for equalization-enhanced phase noise and proposes a method to reverse its effects with a time-varying all-pass filter.

Findings

Phase noise manifests as a time-varying, frequency-dependent phase error.

A model for equalization-enhanced phase noise is developed.

A reversal method using a time-varying all-pass filter is proposed.

Abstract

We show that equalization-enhanced phase noise manifests as a time-varying, frequency-dependent phase error, which can be modeled and reversed by a time-varying all-pass finite impulse response filter.
