FAST EQUALIZATION METHOD FOR RECEIVED PACKET DATA IN BUS TOPOLOGY NETWORK, TRANSMITTING AND RECEIVING METHOD OF PACKET DATA IN BUS TOPOLOGY NETWORK AND METHOD RECEIVER OF BUS NETWORK

摘要

The present invention is chiefly based on a bus topology network, and relates to a packet transmission method which facilitates equalization of a receiver in a transmission and to a reception system and a receiver and a network system which include a corresponding equalizer. A method for transmitting a packet in a bus topology network comprises the steps of: receiving, by a receiver of a reception node connected over a bus topology network, a packet from a transmission node; determining, by the receiver, whether an equalizer training for an training packet previously transmitted by the transmission node has been performed based on an ID included in the packet; loading, by the receiver, an equalizer coefficient for the transmission node when the equalizer training for the transmission node has been previously performed, and setting, by the receiver, an equalizer of the receiver; determining, by the receiver, at least one of an optimum sampling phase difference and a carrier phase difference by using a packet having a training sequence shorter than an training sequence included in the training packet, and correcting, by the receiver, an input signal of the equalizer based on the at least one among the optimum sampling phase difference and the carrier phase difference which has been determined; and setting, by the receiver, the equalizer to have the stored equalizer coefficient, and performing, by the receiver, equalization for the packet.
