摘要：
In SU-MIMO, even when the channel state of one antenna is poor, an error ratio is improved by obtaining a transmission antenna diversity effect. A transmission apparatus 100 that has a plurality of antennas 108-1 to 108-Ntx and transmits a signal according to a MIMO (Multiple Input Multiple Output) system includes a DFT part 111 for precoding transmission data and a spectrum division part 112 for dividing a spectrum output from the DFT part 111. The divided spectrums are transmitted from the different antennas 108-1 to 108-Ntx, respectively.
