Abstract
An object is to suppress a decrease in communication quality and improve the communication quality even when interference is present in some of a frequency band in use in a case where a turbo coding scheme is combined with multicarrier communication using some of a frequency band shared with another system. A frequency selector () selects a band not used by another system, based on a measurement value of a reception level, then selects a subband for systematic-bit mapping from among subbands having a measurement value of the reception level lower than a threshold, and selects a subband for parity-bit mapping from among subbands other than the subband for systematic-bit mapping, for each subband (carrier frequency) of the selected band. A carrier-mapper () maps a systematic bit and parity bit to each subband based on the result of selection by the frequency selector ().
