Problems solved by technology

However, the many tools in DOCSIS 2.0 make the selection of transmission parameters extremely difficult in comparison to DOCSIS 1.0, with the performance of DOCSIS 2.0 systems greatly depending on the choice of these parameters.
However, in current systems, operators tend to choose overly robust transmission parameters just to be on the safe side.
This results in an inefficient use of bandwidth, and a substantial decrease in capacity.

Embodiment Construction

[0034] Although the invention finds particular application to and is described in relation to upstream communication in cable system it also finds application to other forms of communication such as downstream communication and applications besides cable. Although specific embodiments address optimizing receiver parameters, the present invention finds application to optimizing other transmission parameters of a communication system.

[0035] In general, communication systems today lack the ability to dynamically analyze channel conditions and to automatically choose transmission parameters accordingly. This is particularly true for broadband communication systems that are relatively less mature. For example, a new generation of DOCSIS 2.0 cable modem and cable modem termination systems (CMTS) offer cable operators the promise of increased upstream capacity and greater robustness to common channel impairments such as ingress and impulse noise. It is already clear that the many tools in...

Abstract

A method is provided for automatically improving throughput of an active channel in a communication system comprising: receiving input from one or more modules that identify and characterize impairments in the active channel; monitoring the input to track changes in the impairments; and changing channel parameters to improve throughput on the channel based on the changes in the impairments. Other systems and methods are disclosed.

Description

[0001] This application claims priority under 35 USC § 119(e)(1) of Provisional Application Ser. No. 60 / 360,494 filed Feb. 28, 2002. Additional coassigned patent applications also claim priority from this Provisional Application.FIELD OF THE INVENTION [0002] This invention generally relates to communication systems, and more specifically to systems and methods for improving parameter selection. BACKGROUND OF THE INVENTION [0003] The goal of modern communication systems is to provide their operator the best of all worlds. In severe channel conditions it is desirable to provide sophisticated coding schemes and robust transmission at the expense of achieved capacity. In moderate channels conditions it is desirable to provide maximal throughput at the expense of robustness to channel impairments. As a result, the need to provide operators the option to address such a diverse set of channels led many contemporary common standards to include a wide variety of transmission parameters. [000...
