TRANSMISSION DEVICE, RECEPTION DEVICE, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

The present invention improves BER properties in a MIMO system for carrying out MIMO transmission by using a plurality of antennas. A transmission device (1) is provided with: a mapping unit (13) for mapping a transmission signal onto an IQ plane and generating a carrier-modulated carrier symbol; a frequency/inter-transmission-antenna interleaving unit (a frequency/inter-polarized-wave interleaving unit (15)) for interleaving the carrier symbol in the frequency direction and between transmission antennas and generating respective interleaved data for transmission antennas (17); and an output processing unit (16) for configuring an OFDM frame for the respective interleaved data for the transmission antennas (17) and transmitting an OFDM signal via each of the transmission antennas (17).
