Abstract:
1. A method comprising: obtaining a first set of estimated crosstalk coefficients for at least a selected portion of a plurality of communication channels over which signals are to be transmitted from a transmitter to at least a selected portion of a plurality of receivers; adjusting a first set of signals based on the first set of estimated crosstalk coefficients to generate a first set of adjusted signals; transmitting the first set of adjusted signals to corresponding ones of the plurality of receivers; obtaining a second set of estimated crosstalk coefficients for the selected portion of the plurality of communication channels; and adjusting a second set of signals for transmission based on the second set of estimated crosstalk coefficients to generate a second set of adjusted signals; wherein iteration of the obtaining, adjusting and transmitting steps is performed so as to reduce an error between subsequent estimated crosstalk coefficients and actual crosstalk coefficients for the plurality of communication channels; wherein the steps of adjusting the first set of signals and the second set of signals each further comprise iteratively setting power levels of corresponding ones of the signals; and wherein a power level is chosen according to a distribution of the error between subsequent estimated crosstalk coefficients and actual crosstalk coefficients.
