Filed:

May 7, 2007

Appl. No.:

11/745333

Inventors:

Victor Simileysky - San Jose CA, US
Amir Fazlollahi - San Jose CA, US

Assignee:

Centillium Communications, Inc. - Fremont CA

International Classification:

H04L 27/28

US Classification:

375260000

Abstract:

A systems and a method for a DMT-based DSL modem to detect time-varying noise dynamically during transmission and adapt to its rapid changes promptly by increasing or reducing data rate while maintaining the transmission and utilizing maximum channel capacity. A DMT-based modem reserves a first set of sub-channels to detect and measure the time-varying noise. The modem further provides reliable communications for control messages through a second set of sub-channels. The control messages are used to adjust communication to adapt to the new noise conditions over all sub-channels.

International Classification:

H04W 4/02
G01S 13/84

Abstract:

A system and method for an efficient secure phase-based ranging using loopback calibration, including receiving, by a reflector during a current timeslot, an incoming constant tone (CT) signal having a phase shift; determining, by the reflector during the current timeslot or a previous timeslot, a phase shift correction value by using a receiver/transmitter (Rx/Tx) loopback path of the reflector; and/or generating, by the reflector, an outgoing CT signal having an updated phase shift by adjusting the phase shift of the incoming CT signal based on the phase shift correction value.
