An Efficient Low-Complexity Joint Multi-User Power Control and Partial Crosstalk Cancellation in xDSL Systems


Perfect crosstalk cancellation techniques have been proposed to mitigate the effect of crosstalk. However, the online complexity of these crosstalk cancellation techniques grows with the square of the number of lines in the binder. Fortunately, most of the crosstalk originates from a limited number of lines on a limited number of tones. As a result, a… (More)
