PROBLEM TO BE SOLVED: To improve reliability of data transmitted and received in a radio communication system. SOLUTION: A series-parallel conversion section 303 divides data composed by a data composition section 302 of data for transmission and a long training signal, into 12 pieces, and outputs data corresponding to single-time transmission among the 12 divided data pieces to subcarrier modulation sections 3001 to 3012, data corresponding to single-time transmission among the 12 divided data pieces to subcarrier modulation sections 3013 to 3024, and data corresponding to final single-time transmission among the 12 divided data pieces to subcarrier modulation sections 3025 to 3036 respectively. A phase correction section 356 extracts (calculates) average values of the data, divided into 12 by the series-parallel conversion section 303, of three subcarriers, and performs demodulation based upon the average values.
