Impact of Impulse Noise on Adaptive Pre-Equalization Part II

Mia Colabrese2021-08-18T09:36:31-04:00March 1st, 2012|

In part I of this article I discussed adaptive pre-equalization in DOCSIS cable modems and how it can compensate for many upstream impairments such as frequency response, group delay and micro-reflections. I also left off with a cliff-hanger, which is also the title of the article; impulse noise has an impact on adaptive pre-equalization, but how and what is it? I'll cover both what impulse noise is and why and how it impacts adaptive pre-equalization.

Impact of Impulse Noise on Adaptive Pre-Equalization

Mia Colabrese2021-11-24T09:26:04-05:00February 29th, 2012|

For those of you who have attended my seminars you are familiar with adaptive pre-equalization in cable modems (if not I'll explain it in detail momentarily). Also, if you have done any amount of RF plant troubleshooting you are certainly familiar with Impulse noise (again, I'll cover this too). But if you are like me, I never knew that the two topics were co-related.

DOCSIS 3.0 Cable Modem Registration

This article will discuss the channel bonding process and ultimately the DOCSIS 3.0 cable modem registration process. In order to be able to understand this article, I will make many references to my prior article on Cable Modem Registration which focused on DOCSIS 1.x and 2.0 cable modems.

Advanced Troubleshooting in a DOCSIS 3.0 Plant

Mia Colabrese2020-07-02T17:55:04-04:00January 26th, 2012|

If you missed the SCTE Cable-Tec 2011, I am making available my presentation and white paper on Advanced Troubleshooting in a DOCSIS 3.0 Plant. Each speaker had only 20 minutes to cover topics that could easily last hours, so the presentations are understandably brief. Below you will find my presentation in "Slideshare" for online viewing as well as a fully downloadable PowerPoint version. The PowerPoint version also has reader notes attached at the bottom of each slide which you may find useful. In addition, the animations work a little better in the downloadable version.
