Provided is a constellation rotation relay system and constellation rotation relay method which can acquire full diversity gain by performing constellation rotation for a channel matrix in a relay network when configuring a virtual MIMO channel. The constellation rotation system includes a matrix creator for creating a symbol matrix by configuring a symbol transmitted in parallel from a source of a relay network; and a constellation rotation unit constellation rotating the symbol in the symbol matrix by adding a constellation rotation matrix to the created symbol matrix.

Constellation rotation relay system and constellation rotation relay method

A method and system of relaying data are provided. The data is encoded into a turbo codeword by using a convolutional turbo code encoder, and the turbo codeword is transmitted from a source to a relay and a destination after puncturing by a first puncturing operation. The first punctured turbo codeword which is received in the relay is de-punctured and regenerated in a decoding operation and the regenerated turbo codeword is transmitted from the relay to the destination in punctured form after puncturing by a second puncturing operation. The punctured turbo codewords received from the source and the relay by the destination are totaled together as a totaled single turbo codeword and the totaled single turbo codeword is completely decoded to recover the data.

Method and system of relaying data

A proxying process method for traffic of a wireless node and a system using the method are provided. The proxying process method includes: maintaining a virtual node which stores a communication packet from a server, destined for a first node; and transmitting the stored communication packet from the virtual node to a second node when a transmission request for the communication packet is transmitted to the first node by the second node.
