摘要: A power control method for transceiver units conveying data over discrete tones. The method includes the steps of: determining a transmit power over a physical channel for each individual tone, such that this transmit power maximizes a weighted function of data rates achievable with this tone over the physical channel and over modeled neighboring channels, with the constraint that this transmit power conforms to a transmit power mask, summing up the data rates over the whole set of tones, adjusting the weights such that the total data rates over the modeled neighboring channels reach some target data rates, and such that the total data rate over the physical channel is maximized, with the constraint that each weight is identical over the whole set of tones.

摘要: The present invention relates to a method for determining a transmit PSD over a remotely-deployed line, which method comprising the steps of: modeling a first far-end crosstalk originating from the line and coupling into a centrally-deployed victim neighboring line, modeling a second far-end crosstalk originating from a further centrally-deployed neighboring line and coupling into the victim neighboring line, determining the transmit PSD from the first modeled far-end crosstalk and the second modeled far-end crosstalk. A method according to the invention further comprises the steps of: expressing the transmit PSD as a function of a line parameter characterizing a line segment of the further neighboring line, carrying out channel measurements of a spare line that connects the central location to the remote location, and that shares common transmission characteristics with the line segment, estimating from said channel measurements a value of the line parameter, determining therefrom the transmit PSD. The present invention also relates to a power control unit.
