Abstract
An access node of a communication system is configured to control crosstalk between channels of the system. A set of L distinct and linearly independent pilot signals is generated, with each pilot signal having length n, where n>L such that n−L linearly independent n-tuples are available for use in detection and correction of impulse noise. In an illustrative embodiment, the L pilot signals are mutually orthogonal. The L pilot signals are transmitted over respective ones of the channels, and one or more of the pilot signals as received over their respective channels are processed to detect the presence of impulse noise. A crosstalk estimate corrected for the detected impulse noise is generated and utilized to control crosstalk between two or more of the channels.
