摘要： An apparatus for data transmission is provided. The apparatus includes a data processor encoding an information bit and generating a modulation symbol by performing constellation mapping on the encoded information bit, a discrete Fourier transform (DFT) unit performing DFT on the modulation symbol to generate a frequency-domain symbol, a space time block coding (STBC) processor performing STBC on the frequency-domain symbol to generate an STBC code consisting of 1st and 2nd STBC streams, a subcarrier mapper mapping the 1st STBC stream to a 1st subcarrier and mapping the 2nd STBC stream to a 2nd subcarrier, an inverse fast Fourier transform (IFFT) unit performing IFFT on the 1st subcarrier to generate a 1st single carrier-frequency division multiple access (SC-FDMA) symbol and performing IFFT on the 2nd subcarrier to generate a 2nd SC-FDMA symbol, and a plurality of transmit antennas transmitting the 1st and 2nd SC-FDMA symbols. STBC is effectively applied to a SC-FDMA system to decrease a peak-to-average power ratio (PAPR) and to maintain a single-carrier property.

摘要： Provided is a data transmission apparatus using multiple antennas. The apparatus includes: a data processing unit that generates a data symbol by performing channel-coding for and constellation mapping on an information bit, a DFT unit that generates a frequency domain symbol by performing DFT (Discrete Fourier Transform) for the data symbol, an MIMO processing unit that generates a first transmission symbol by applying a first transmit diversity scheme to the frequency domain symbol and creates a second transmission symbol by applying a second transmit diversity scheme to the first transmission symbol, an SC-FDMA modulating unit that generates an SC-FDMA (Single Carrier-Frequency Division Multiple Access) symbol by performing IFFT (Inverse Fast Fourier Transform) on the first and second transmission symbols, and plural transmission antennas that transmit the SC-FDMA symbol. The MIMO processing unit divides the plural transmission antennas into two groups and maps the first and second transmission symbols to the first and second groups respectively. STBC and different transmit diversity schemes can be applied to the data transmission apparatus that includes the plural transmission antennas while maintaining the single carrier feature, so an SC-FDMA system can be easily configured.

摘要： A method for detecting signals based on despreading and a signal transmitting method for the same are disclosed. Signals are spread according to the size of at least one spreading band, which is determined in consideration of a correlation degree of a frequency band in a communication system. A reception side which receives the signals detects the signals after despreading with respect to signals which are spread in a frequency band having a correlation degree equal to or greater than a predetermined level as a spreading band, among the reception signals. Thus, the dimension of the detected signals can be decreased.
