The transmitter executes the operations of: transmitting a data signal to a remote network apparatus according to output packets of the MAC when the transmitter enters a normal state; transmitting an idle signal to the remote network apparatus when the transmitter enters an idle state; transmitting an indication signal to the remote network apparatus to notify it to enter a low power state, wherein the indication signal is different from the idle signal; entering the idle state or the normal state from the low power state in response to at least one of a predetermined period and a transmitting enable signal. | 07-30-2009 |
20100054315 | Apparatus and Method for Start-up in Communication System - 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. | 03-04-2010 |
