Patent ID: 8520598

Claim:
An apparatus for transmitting data, the apparatus comprising: a data processing unit configured to generate a data symbol by channel-coding and constellation-mapping on information bits; a Discrete Fourier Transform (DFT) unit configured to generate a frequency domain symbol by performing DFT on the data symbols; a Multiple-Input Multiple-Output (MIMO) processing unit configured to: generate a first transmission symbol by applying a first transmission diversity scheme to the frequency domain symbol; and generate a second transmission symbol by applying a second transmission diversity scheme to the first transmission symbol, the first transmission diversity scheme applied to the frequency domain symbol being different from the second transmission diversity scheme applied to the first transmission symbol; a Single Carrier-Frequency Division Multiple Access (SC-FDMA) modulation unit configured to generate an SC-FDMA symbol by performing Inverse Fast Fourier Transform (IFFT) on the first transmission symbol and the second transmission symbol; and a plurality of transmission antennas configured to send the SC-FDMA symbol, wherein the MIMO processing unit is further configured to: divide the plurality of transmission antennas into a first group and a second group, and map the first transmission symbol to the first group and the second transmission symbol to the second group.
