Abstract:
1. A method of controlling crosstalk between channels of a communication system, the method comprising the steps of: obtaining crosstalk estimates for respective ones of the channels; processing the crosstalk estimates to generate denoised crosstalk estimates; and adjusting power levels of signals transmitted over one or more of the channels based on the denoised crosstalk estimates; wherein the step of processing the crosstalk estimates comprises for a given one of the channels the steps of converting the crosstalk estimate for the given channel to a discrete transform domain, substantially eliminating in the discrete transform domain one or more designated portions of the crosstalk estimate for the given channel, and converting remaining portions of the crosstalk estimate for the given channel back from the discrete transform domain to obtain the corresponding denoised crosstalk estimate for the given channel.
