| 摘要 |
According to an aspect of the present invention, an apparatus for data transmission is provided. The apparatus includes a data processing unit generating a data symbol by performing channel coding and constellation mapping on an information bit, a single carrier-frequency division multiple access (SC-FDMA) modulator generating an SC-FDMA symbol by performing discrete Fourier transform (DFT) on the data symbol, by mapping the DFT performed-data symbol to subcarriers, and by performing inverse fast Fourier transform (IFFT) on the subcarrier mapped-DFT performed-data symbol, and a plurality of transmit antennas transmitting the SC-FDMA symbol. A single carrier-frequency division multiple access (SC-FDMA) system can effectively use frequency switched transmit diversity (FSTD) to reduce a peak-to-average power ratio (PAPR) and to maintain a single-carrier property.
