Abstract
A transceiver in a communication system and a start-up method thereof are provided. The transceiver comprises an auto-negotiation circuit, a timing recovery circuit, an interference cancellation circuit and an equalizer. The auto-negotiation circuit performs an auto-negotiation procedure to determine whether the transceiver operates as a master or slave transceiver. If the transceiver operates as a slave transceiver, it executes a first stage and a second stage during the start-up process. In the first stage, the transceiver performs channel estimation to generate a channel estimation value, presets the parameters of the equalizer according to the channel estimation value, and trains the timing recovery circuit and the equalizer; in the second stage, the transceiver trains the interference cancellation circuit.
