Patent ID: 8687735

Claim:
A transmitter including a plurality of antennas, the transmitter characterized by comprising: a Discrete Fourier Transform (DFT) unit configured to transform a time domain signal into a frequency domain signal: a cluster mapping unit configured to divide the frequency domain signal into clusters and to assign each of the clusters to consecutive frequencies on the basis of cluster assignment information: an Inverse Discrete Fourier Transform (IDFT) unit configured to transform a mapped frequency domain signal into a time domain signal: a cyclic delay setting unit configured to set, for each of the antennas, a cyclic delay amount of the IDFT-transformed time domain signal: and a cyclic delay amount determination unit configured to determine, on the basis of a cluster size, which is the number of subcarriers to be included in a single cluster, the cyclic delay amount to be set by the cyclic delay setting unit.
