Embodiment Construction

[0042] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, in the embodiment of the method and device for processing data packets in the two-way relay system of the present invention, the processing of data packets includes the following steps:

[0044] Step S11 Send the data frame to the relay node: In this step, the first node and the second node respectively send the data to be sent to the other party (the second node or the first node) in this node to the relay node. These data are synchronously sent to the above-mentioned relay nodes in the form of data frames, and these data are filled into the above-mentioned data frames in the form of data bits after being modulated by BPSK / QPSK in the above-mentioned first node or the second node. These data frames are sent to the relay node by the above-mentioned first node and the second node at the same time.

[0045] Step S12 Rece...

Abstract

The invention relates to a data packet processing method for a two-way relay system, which comprises that: a first node and a second node code own information required to be transmitted to each other respectively, and synchronously transmit the coded information to a relay node in form of data frame; the relay node receives a composite signal data frame; the relay node processes the contents of the composite signal data frame bit by bit, and further performs comprehensive processing according to coding redundancy to obtain an intermediate signal data frame; the intermediate node transmits theintermediate signal data frame; and the first and second nodes receive the intermediate signal data frame respectively, and subtract corresponding data frames transmitted per se from the intermediatesignal data frame to obtain data frames transmitted from the opposite nodes. The invention also relates to a data packet processing device for the two-way relay system. The data packet processing method and the data packet processing device for the two-way relay system have the advantages of no requirement on complete decoding on the relay node, relatively higher coding rate and great reduction in error rate.

Description

technical field [0001] The invention relates to the field of data communication, more specifically, to a method and device for processing data packets in a two-way relay system. Background technique [0002] In data two-way relay communication (especially microwave two-way relay communication), a relay node simultaneously receives data sent from two adjacent nodes (one is the first node and the other is the second node), and The data sent by the first node is sent to the second node, and the data sent by the second node is sent to the first node at the same time. figure 1 shows a node schematic diagram of a two-way relay system, in figure 1 , node N 1 , N 2 are the first node and the second node respectively, and the node N 3 is a relay node; the first node and the second node respectively send data to the third node synchronously, and the third node respectively forwards the data sent by any node to the opposite node. The two signals of the relay node sent by the above...
