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

摘要

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.

1. A transmission device for transmitting an OFDM signal using a plurality of transmit antennas, comprising:
a mapping unit configured to map a transmission signal onto an IQ plane to generate a carrier-modulated carrier symbol; a frequency/transmit antenna interleaving unit configured to interleave the carrier symbol in a frequency domain and between transmit antennas to generate interleaved data for each transmit antenna; and an output processing unit configured to construct an OFDM frame for the interleaved data for each transmit antenna and transmit an OFDM signal via the transmit antennas.
