Abstract
An access node of a communication system is configured to control crosstalk between channels of the system. Vectoring circuitry in the access node estimates crosstalk between channels of the system, generates a compressed representation of the crosstalk estimates, and generates compensated signals based on the compressed representation of the crosstalk estimates. The compressed representation comprises a value array and an index array, with the value array comprising selected values from each of a plurality of rows of a matrix representation of the crosstalk estimates, and the index array identifying locations of the selected values in the matrix representation of the crosstalk estimates. The compensated signals may be pre-compensated signals or post-compensated signals.
