Mitigation of spectral interference in communications systems such as Digital Subscriber Loop (DSL) systems, and in particular mitigation of spectral interference using dynamic spectral shaping (DSS) in DSL systems, and in particular Single-pair High-speed DSL (SHDSL) systems.

Method and system for applying dynamic spectral shaping to digital subscriber loop communication systems

A DSL communication system and a method for configuring a DSL communication system. The method includes training at least one anchor DSL modem transmitter to transmit information over at least one anchor line at an anchor bit rate that is determined based on an allowable tolerable noise level and a minimum allowable signal-to-noise ratio (SNR) margin; training one or more other DSL modem transmitter to transmit information over one or more other line at a bit rate that is determined by a current noise level and a target SNR margin, wherein the target SNR margin is higher than the minimum allowable SNR margin; and transmitting information by at least one trained DSL modem transmitter to at least one DSL modem receiver.

Method and system for robust digital subscriber loop communication

In a communications system having a first modem transmitting via a communications channel, a method for adding a second modem, the method including learning crosstalk caused by transmissions from the first modem to the second modem while the second modem is in a transmitting state insufficient to cause crosstalk interference to the first modem in accordance with a predefined measure, deriving from the learned crosstalk an estimation of crosstalk that would be caused by the second modem to the first modem when the second modem is in a transmitting state, configuring the first modem to cancel crosstalk according to the crosstalk estimation, causing the second modem to enter a transmitting state sufficient to cause crosstalk interference to the first modem in accordance with a predefined measure, and causing the first modem to at least partially cancel crosstalk caused by the second modem in accordance with the crosstalk estimation.
