According to the present invention, a transmitter includes: multiple antennas 15-1, 15-2; a DFT unit 04 configured to transform a time domain signal into a frequency domain signal; a cluster mapping unit 05 configured to divide the frequency domain signal into clusters and to assign the clusters to frequencies on the basis of cluster assignment information; an IDFT unit 06 configured to transform a mapped frequency domain signal into a time domain signal; and cyclic delay setting units 11-1, 11-2 configured to set, for the respective multiple antennas, a cyclic delay amount to the IDFT-transformed time domain signal. |
