摘要:
A receiving apparatus includes: a transmission path characteristics estimating section obtaining pre-interpolation transmission path characteristic data as estimate values for transmission path characteristics as characteristics of a transmission path of an OFDM signal for transmission symbols of pilot signals by using the pilot signals contained in the OFDM signal, and filtering the pre-interpolation transmission path characteristic data by using an interpolation filter, thereby obtaining transmission path characteristic data as estimate values for transmission path characteristics for transmission symbols of the OFDM signal; a distortion correcting section performing distortion correction for the OFDM signal by using the transmission path characteristic data; and a filter controlling section controlling a pass band of the interpolation filter.
