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.
