Abstract: A data relay method and a system for the same are provided to obtain a relatively big code gain as a source station, a relay station, and a destination station identically use convolutional turbo codes, not cyclic convolutional codes, in relaying data through a relay network. A data relay system(200) comprises the first puncturing unit(210), the second puncturing unit(220) and a data restoration unit(230). The first puncturing unit(210) codes data into a turbo codeword using convolutional turbo codes, primarily punctures the turbo codeword, and transmits the primarily punctured codeword to a relay station and a destination station from a source station. The second puncturing unit(220) decodes the primarily punctured codeword, secondarily punctures the decoded codeword, and transmits the secondarily punctured codeword to the destination station from the relay station. The data restoration unit(230) combines the turbo codewords, respectively received to the destination station from the source station and the relay station, into a turbo codeword, decodes the combined codeword, and restores the data.

Abstract: A coordinate rotation relay system and a method thereof are provided to induce each channel in a channel matrix not to have '0' in forming a virtual MIMO(Multiple Input Multiple Output) channel by carrying out coordinate rotation for the symbols transmitted from a source. A coordinate rotation relay system(200) comprises a matrix creation unit(210) and a coordinate rotation unit(220). The matrix creation unit(210) arranges symbols, transmitted from a source in a relay network, in parallel and creates a symbol matrix. The coordinate rotation unit(220) adds a coordinate rotation matrix to the created symbol matrix and performs coordinate rotation for the symbols of the symbol matrix. The matrix creation unit(210) arranges channels of a link, which will be utilized by the coordinate-rotated symbols to be transmitted to a destination in the relay network, in parallel and creates a channel matrix. The coordinate rotation unit(220) carries out coordinate rotation for each channel in the created channel matrix in order to have another value, not '0', in consideration of the coordinate-rotated symbols.

Abstract: Provided is a negative electrode active material of a lithium ion capacitor, which is characterized in that the active material includes modified graphite with an exposed edge surface. According to the present invention, a manufacturing method of the negative electrode active material of the lithium ion capacitor comprises adding graphite in hydrogen peroxide, heating the same, and sonicating the same. The present invention modifies the graphite by inducing etching of the graphite caused by the hydrogen peroxide. Therefore, the movement of lithium ions is facilitated through the edge surface of the modified graphite, and the graphite is prevented from being separated by forming a chemically bonded SEI layer and preventing an anion of an electrolyte from being intercalated into the graphite. As a result, the lithium ion capacitor including the negative electrode active material according to the present invention can obtain an energy density which is about 55% higher than that of a conventional lithium ion capacitor with unmodified graphite.
