<P>PROBLEM TO BE SOLVED: To provide a reception device that achieves high speed path estimation with lowering path estimation precision even when a reception environment of the reception device changes. <P>SOLUTION: The reception device comprises a reception unit which receives a frequency multiplex signal, a first Fourier transformation unit which transforms the received frequency multiplex signal to a frequency domain based upon a window specifying a time zone in which the Fourier transformation is performed, a first time waveform generation unit which inversely Fourier-transforms a plurality of pilot signals inserted into the frequency multiplex signal transformed to the frequency domain at constant frequency intervals to generate a first time waveform, a second time waveform generation unit which generates a second time waveform based upon the received frequency multiplex signal, a second Fourier transformation unit which combines the first and second time waveforms with each other and transforms the composite time waveform into information on a frequency domain, and a propagation path compensation unit which performs propagation path compensation on the frequency multiplex signal according to the information obtained by the second Fourier transformation unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
