摘要： A method for pre-distorting a power amplifier comprises the steps of: inputting a baseband digital training signal with time-varying amplitude into a transmitting end in a single operation; converting the baseband digital training signal to a radio-frequency analog training signal, and converting the radio-frequency analog training signal to a radio-frequency analog transmitting signal via a power amplifier; receiving the radio-frequency analog transmitting signal at a receiving end, and converting the received signal to a baseband digital receiving signal; and calculating parameters for pre-distorting the power amplifier by estimating the characteristic curve of the power amplifier according to the baseband digital receiving signal.

摘要： A method for enhancing Ethernet channel impairment comprises the steps of sending a sequence to a receiver in a slave transceiver by a master transceiver, and training cancellation filter coefficients of an echo canceller and a near-end cross talk canceller in the master transceiver before the receiver of the slave transceiver converges.
