Method And Apparatus For Adapting To Dynamic Channel Conditions In A Multi-Channel Communication System

View page
US Patent:
20080089433, Apr 17, 2008
Filed:
Oct 13, 2006
Appl. No.:
11/580706
Inventors:
Jun Hyok Cho - Irvine CA, US
Eugenio James Infusino - Long Beach CA, US
Evangelos Petsalis - West Hollywood CA, US
Michail Konstantinos Tsatsanis - Huntington Beach CA, US
International Classification:
H04L 1/02
US Classification:
375267, 375350
Abstract:
A disturbance detection and fast re-train method and apparatus configured for use in a multi-channel communication is disclosed. During data communication disturbance detection occurs by monitoring error rates or other factors, such as crosstalk profiles. Upon detection of a disturbance, the system generates and transmits a line upset condition signal to an opposing terminal and monitors for a similar response from the opposing terminal. Channels which fail to convey such signals may be switch out of service. The signals received via the channels may be utilized as training signals to thereby yield a new crosstalk profile. The new crosstalk profile is processed to establish one or more new multiple input, multiple output filter coefficients, bit loading settings, and gain level settings. These new settings may exchanged with the opposing terminal. In addition, channels which, although transporting signals, yield CRC error rates over a pre-determined threshold, are removed from service.

Spectrally Flat Time Domain Equalizer And Methods

View page
US Patent:
6829296, Dec 7, 2004
Filed:
Sep 20, 2000
Appl. No.:
09/665784
Inventors:
Markos G. Troulis - Irvine CA
Evangelos Petsalis - Irvine CA
Xuming Zhang - Mission Viejo CA
Assignee:
Mindspeed Technologies, Inc. - Newport Beach CA
International Classification:
H03H 730
US Classification:
375232, 375231, 375233, 375229
Abstract:
The time domain equalizer filter of the present invention increases the data rate of a communications system while shortening a channel. Such a time domain equalizer filter is spectrally flat and the central tap is constrained to a non-zero real number. The error between the data filtered by the time domain equalizer filter and the data filtered by a target filter is reduced by adapting the time domain equalizer filter and the target filter. Adaptation of the time domain equalizer filter and the target filter may be accomplished by calculating new tap values for each filter while constraining the central tap of the time domain equalizer filter. In this way, the error between the data filtered by the time domain equalizer filter and the data filtered by the target filter may be reduced, so that a shortened channel may be provided. Accordingly, by shortening the channel and balancing the use of a spectrally flat time domain equalizer filter, the data rate of the communications system may be increased.
