  • Patent number: 8340279
    Abstract: An adaptive interference cancellation system is described. In one example the system operates by receiving a data signal using a DSL (Digital Subscriber Line) and receiving a reference signal, the reference signal corresponding, in part, to noise on the data signal. The reference signal is classified and a noise cancellation signal is applied to the data signal based on the classification.
    Type: Grant
    Filed: October 5, 2007
    Date of Patent: December 25, 2012
    Assignee: Adaptive Spectrum and Signal Alignment, Inc.

  • Patent number: 7349963
    Abstract: Operational data collected from a communication system, such as a DSL system, may include exclusionary data and/or indicative data that can be analyzed to determine the type of communication device, such as a DSL modem, that generated the operational data. Exclusionary data, if any, can be used to exclude one or more communication device types from consideration. Indicative data, if any, may be used to influence the selection of a communication device type, such as by assigning scores to communication device type features and/or to communication device types. Information pertaining to various communication devices may be maintained in a database or the like. In a DSL system, modem types may be evaluated and selected by a modem identification unit or identifier that collects and analyzes the operational data using collecting means and identifying means. The identifier may be part of a controller, such as a DSM Center or the like implemented in and/or with a computer and coupled to the DSL system.
