Abstract
A method comprising allocating one or more detection tones of a sync symbol for crosstalk-free feedback data estimation, wherein the one or more detection tones are a quiet signal; transmitting the one or more detection tones to a computing device, receiving the crosstalk-free feedback data from the computing device, wherein the crosstalk-free feedback data comprises data associated with a background noise detected during the detection tones; determining an optimized PSD based at least in part on the crosstalk-free feedback data; and adjusting a transmission PSD of a plurality of tones based at least in part on the optimized PSD.
