  • Performance of DSL modem under impulse noise
    Publication number: 20070195871
    Abstract: Improving performance of DSL modem under impulse noise is disclosed. A method of improving a performance of a digital subscriber line (DSL) modem having an impulse noise of long duration includes assigning a value to each of framing parameters based on a rate adaptation algorithm which considers a signal to noise ratio (SNR) of a channel coupled to the DSL modem and a number of constraints applied to the DSL modem. The method also includes generating another set of values of the framing parameters maximizing an impulse noise protection (INP) of the DSL modem while meeting the number of constraints based on a limited set of possible values of the redundancy bytes per Reed Solomon codeword (Rp) of the framing parameters and a limited collection of possible values of the interleaver depth (Dp) of the framing parameters.

  • Training and updating for multiple input-output wireline communications
    Publication number: 20050195892
    Abstract: The present invention provides a crosstalk mitigator for use in vectoring a digital subscriber line (DSL) system having initial crosstalk interference. In one embodiment, the crosstalk mitigator includes a crosstalk parameter estimation portion configured to determine crosstalk parameters associated with the initial crosstalk interference, and a mitigator initialization portion coupled to the crosstalk parameter estimation portion and configured to train the DSL system to provide a mitigated crosstalk based on the crosstalk parameters prior to a data transmission mode. In an alternative embodiment, the capability to detect a change in the mitigated crosstalk during the data transmission mode and update the crosstalk parameters to rectify the change in the mitigated crosstalk is provided.
