<p><P>PROBLEM TO BE SOLVED: To provide a radio receiver for implementing detection of a unique word and synchronization of a radio frame with high accuracy in a short time. <P>SOLUTION: A radio receiver 2 comprises: a demodulation signal generation part 22 which generates demodulation signals corresponding to a non-modulation signal, alternate modulation signal, and data modulation signal by respectively demodulating the non-modulation signal, alternate modulation signal, and data modulation signal which are generated by modulating a constant value signal, alternate signal, and data signal respectively for each radio frame; a non-modulation signal/alternate modulation signal detection timing generation part 24 which generates detection timing for the non-modulation signal and alternate modulation signal for each radio frame; and a hard determination part 23 which outputs a reception data signal corresponding to a data region excluding a unique word region from the demodulation signal of a relevant radio frame on the basis of information on the detection timing for the non-modulation signal and alternate modulation signal for each radio frame. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
