摘要

A wideband carrier frequency error calculator that, for each of a plurality of location patterns, calculates a cumulative value through a predetermined process performed on signals output by an orthogonal transformer for a plurality of sub-carrier positions determined according to a given location pattern while simultaneously shifting the signals output therefrom by one sub-carrier unit along the carrier direction and that also calculates wideband carrier frequency error according to carrier direction discrepancies calculated as maximum values within the cumulative value, and a carrier frequency error corrector that applies corrections to carrier frequency discrepancies according to the wideband carrier frequency error so calculated.
