ABSTRACT:
A radio receiver apparatus and a radio transmitter apparatus wherein the energy loss caused by addition of GI is suppressed, while the reception quality is improved. A signal having been subjected to an IFFT process is repetitively transmitted N times with a length of one OFDM symbol interval. At a receiver apparatus receiving the transmitted signals, a leading data extracting part (207) extracts, from the leading data portions of the direct waves of the received signals, portions that are not interfered with by temporally adjacent data. A combing part (209) combines the received signals in such a manner that align the rear end of each repetitively transmitted data portion except the leading data portion with the rear end of the leading data portion extracted by the leading data extracting part (207). The combined signal is then subjected to an FFT process in an FFT part (210).
