Patent number: 9673860Abstract: In accordance with an embodiment, the method includes inserting a plurality of crosstalk probing signals within the wired multi-carrier communication system for probing the crosstalk from respective ones of the plurality of disturber lines into the victim line, carrying out crosstalk measurements over the victim line, and estimating the crosstalk coefficients from the crosstalk measurements. The method further includes organizing the plurality of disturber lines into subsets of disturber lines, and individually assigning disjoint groups of carriers to the respective subsets of disturber lines. The insertion of the plurality of crosstalk probing signals is confined within the respectively assigned groups of carriers. The subsets of disturber lines and/or the groups of carriers used for a second or subsequent iteration are tailored based on crosstalk characteristics observed for the respective disturber lines during a pervious iteration.Type: GrantFiled: July 18, 2013Date of Patent: June 6, 2017Assignee: Alcatel LucentInventors: Adriaan De Lind Van Wijngaarden, Mamoun Guenach, Carl J.

Publication number: 20140044247Abstract: A network includes an access link and a local area link. The access link and the local area link are interferingly coupled. A method for performing spectrum management in view of a constraint in the network includes quantifying interference between the access link and the local area link, determining a first spectral configuration for a first transmitter operating over the access link, and determining a second spectral configuration for a second transmitter operating over the local area link. The determining of the first spectral configuration and the determining of the second spectral configuration are performed such that the respective achievable channel capacities of the access link and the local area link meet the constraint.Type: ApplicationFiled: March 19, 2012Publication date: February 13, 2014Applicant: ALCATEL-LUCENTInventors: Jochen Maes, Michael Timmers, Mamoun Guenach

Patent number: 7830978Abstract: A method involves performing a plurality of acts. The acts include transmitting a first signal stream to a first channel of a multi-channel communications medium while transmitting a second signal stream to a different second channel of the medium. The second signal stream is substantially temporally correlated to the first signal stream. The method includes receiving an SINR measured at a receiver configured to receive signals from the first channel. The SINR is measured while the receiver received the first signal stream. The method includes determining a channel matrix element between the first and second channels or a ratio of said channel matrix element to a diagonal element of the channel matrix. The act of determining is based on the received SINR.Type: GrantFiled: August 31, 2007Date of Patent: November 9, 2010Assignees: Alcatel Lucent, Alcatel-Lucent USA Inc.Inventors: Mamoun Guenach, Gerhard Guenter Theodor Kramer, Jerome Louveaux, Jochen Maes, Michael Peeters, Luc Vandendorpe, Jan Sylvia Verlinden, Philip Alfred Whiting, Geert Bert Ysebaert, Miroslav Zivkovic
