1. A system comprising:
- a transceiver configured to operate in full-duplex mode;
a magnitude determining device configured to generate a magnitude value of a signal received by the transceiver; and
a controller configured to generate a control signal based on the magnitude value,wherein the control signal adjusts current driving the transceiver during transmission of a transmitted signal.

Abstract
Systems and methods are used to adjust, e.g., reduce, current driving a transmitter, i.e., to reduce transmitter power consumption, based on an actual value of a received signal from received along a cable. For example, this is very beneficial to an Ethernet system where the received signal is attenuated by the lossy cable. In this case, the transmitter power consumption can be lowered during a normal application where data is transmitted and received through the cable.
