Abstract:
1. A method performed by a processor for optimizing coefficient data for a vectored DSL system, comprising: identifying a plurality of macrobands in the vectored DSL system; selecting respective coefficient data compression parameters for each of the macrobands, wherein the coefficient data compression parameters specify parameters of one or more data compression schemes used to compress coefficient data from an original number of bits to a lower compressed non-zero number of bits; evaluating performance of the vectored DSL system with the selected coefficient data compression parameters; and optimizing the selecting of the respective coefficient data compression parameters in accordance with a desired system performance as determined by the evaluating, wherein the optimized coefficient data compression parameters of a first one of the macrobands are different than the optimized coefficient data compression parameters of a second one of the macrobands; storing the optimized coefficient data compression parameters in a vectoring module.
