<P>PROBLEM TO BE SOLVED: To provide a radio receiver for correctly acquiring control information which is required to demodulate a data signal. <P>SOLUTION: A radio receiver 100 includes a first demodulation part 101, a second demodulation part 102, and a determination part 103 in order to receive a frame including a preamble signal and a data signal. The first demodulation part 101 demodulates a first channel symbol and a second channel symbol following the first channel symbol, which are included in each control signal, and then, acquires first and second channel symbol numbers. The second demodulation part 102 demodulates each segment index signal, and then, acquires a segment index. The determination part 103 corrects the first channel symbol number by using the segment index acquired by the second demodulation part, and then, determines control information, based on the corrected first channel symbol number. <P>COPYRIGHT: (C)2012,JPO&INPIT |
