Disclosed is an OFDM signal receiving apparatus for diversity reception, with a plurality of antennas, of an OFDM signal containing Y sub-carriers, where 2X-1<Y<2X and X>1. The OFDM signal receiving apparatus includes a plurality of receiving systems, and a diversity processing unit connected to the receiving systems and fed with sequences of data on sub-carriers demodulated by the respective receiving systems. At least one of the receiving systems includes an FFT circuit for Fast Fourier transforming, in parallel, only a sequence of data on 2Z sub-carriers contained in the OFDM signal received with a corresponding antenna, where X>Z. The diversity processing unit performs a diversity process on sequences of data on sub-carriers, out of all the Y sub-carries, redundantly demodulated.
