摘要： A point-to-multipoint traffic routing method that routes a multicast traffic through a determined tree on an MPLS network. A node on an MPLS network conducting a point-to-multipoint traffic routing method receives a message with an object including topology information on a determined tree, determines whether itself is a copy node or not based on the topology information, and copies, if determined to be a copy node, the received message to transmit to at least two nodes specified as next by the topology information. The present routing method ensures smooth operations of a copy and a merge node as well as an overall network.

摘要： In an orthogonal frequency division multiplexing (OFDM) system, a receiver includes a received signal transformer, a frequency offset estimator and a frequency compensator. The received signal transformer removes from a training symbol a guardtone and a sub-carrier deviated from a mean value of effective sub-carrier signals by over a predetermined value. The frequency offset estimator estimates the frequency offset of the OFDM digital signal and the frequency compensator compensates the frequency offset of received signals by using the estimated frequency offset. Thus, data transmission efficiency can be greatly improved and influence from a frequency-selective noise channel can be minimized. Further, by removing data unnecessary for the frequency offset estimation, the calculation amount can be reduced.
