There is disclosed a receiver apparatus that can receive OFDM signals. The apparatus comprises: an FFT unit for transforming signals inputted to the apparatus into frequency-domain signals, thereby outputting the transformed signals on a complex symbol-by-complex symbol basis; correlation-calculating units each of which calculates an index indicating a correlation between complex symbols in a respective one of a plurality of groups, each of the plurality groups being a set of a plurality of complex symbols separated from each other by an interval in which a pilot signal is inserted, the groups being selected such that the complex symbols constituting the groups differing from each other; and a judging unit for determining, based on the calculated index for each group, whether or not any index satisfying a predetermined condition is existent, thereby outputting a result of the judgment. |
