Abstract
Embodiments of methods, apparatuses, and systems for preprocessing a transmit signal of a transceiver are disclosed. One method includes estimating parameters of a communication link between the transceiver and a link partner transceiver, estimating cross-talk coupling of the transceiver to at least one other transceiver, and adjusting at least one of a transmit power or a transmit signal waveform based on the estimated parameters and estimated cross-talk. One apparatus includes a transceiver that is operative to obtain parameters of a communication link between the transceiver and a link partner transceiver, and to obtain a representation of cross-talk coupling of the transceiver to at least one other transceiver. Further, a controller of the transceiver is operative to adjust at least one of a transmit power level or a transmit signal waveform based on the estimated parameters and estimated cross-talk.
