Abstract
In a MIMO system performing MIMO transmission using a plurality of antennas, BER characteristics are improved. A transmission device includes a mapping unit that maps a transmission signal onto the IQ plane to generate carrier-modulated carrier symbols, a frequency/transmit antenna interleaving unit (frequency/polarized wave interleaving unit) that interleaves the carrier symbols in the frequency domain and between transmit antennas to generate interleaved data for each transmit antenna, and an output processing unit that constructs an OFDM frame for the interleaved data for each transmit antenna and transmits an OFDM signal via the transmit antennas.
