Transceiver spectrum control for cross-talk mitigation

摘要

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.

主权项

1. A method of preprocessing a transmit signal for transmission by a sub-transceiver of an Ethernet transceiver, the Ethernet transceiver including a plurality of the sub-transceivers, the method comprising:
exchanging parameters of a communication link between the Ethernet transceiver and a link partner transceiver; estimating cross-talk coupling of the Ethernet transceiver to at least one other transceiver; adjusting at least one of a transmission protocol or a data rate based on the exchanged parameters; and independently adjusting a transmit power level of each of the plurality of the sub-transceivers based on the parameters, the adjusted transmission protocol or data rate, and estimated cross-talk.
