Abstract:
1. A receiving device comprising: a de-mapping unit configured to receive a symbol signal generated by performing mapping on a first branch signal and a second branch signal indicating information about a transmission target, and perform de-mapping on the symbol signal by a hard decision; a selecting unit configured to receive the first branch signal and the second branch signal, and to receive a reception state signal from a comparing unit, the selecting unit providing a selected signal by selecting either the first branch signal or the second branch signal depending upon the reception state signal; a decoding unit configured to decode the information about the transmission target based on the selected signal; a cyclic shifting unit configured to perform cyclic shifting on the second branch signal obtained through the de-mapping, the cyclic shifting being performed in reverse order of cyclic shifting order in a transmitting device, and the selecting unit selects a signal from the second branch signal indicating predetermined bits excluding a bit located in a predetermined region starting from a beginning of a sequence after the cyclic shifting performed by the cyclic shifting unit, and the first branch signal indicating the predetermined bits, the predetermined bits being of a plurality of bits indicated by the second branch signal obtained through the de-mapping, wherein the cyclic shifting is performed on the second branch signal in the transmitting device that transmits the symbol signal.
