ABSTRACT:
Channel estimation unit16includes CNR calculation unit17, threshold setting unit18, and modulation method determination unit19. CNR calculation unit17calculates a CNR for each of a plurality of subcarriers from a received multicarrier communication signal. Threshold setting unit18takes statistics of a plurality of calculated CNRs, and, based on the statistics, sets CNR thresholds each assigned to one of a plurality of modulation methods. Modulation method determination unit19uses the set thresholds to determine a modulation method for each subcarrier, according to the calculated CNR of the subcarrier.
