Abstract:
1. A communication apparatus comprising: a transforming section configured to transform a symbol in a time domain into a signal in a frequency domain with a discrete Fourier transform (DFT) having a size that is a product of powers of a plurality of values; a mapper configured to map the signal in the frequency domain on a plurality of frequency bands, each frequency band including a plurality of subcarriers, each frequency band being located at a position separate from position(s) of other of the plurality of frequency bands, and a size of at least one of the plurality of frequency bands being a multiple of a product of two or more powers of prime numbers; and a generator configured to generate a single carrier-frequency division multiple access (SC-FDMA) signal in the time domain from the mapped signal.
