<P>PROBLEM TO BE SOLVED: To enable high quality diversity reception in a receiving station in which the number of reception antennas is restricted. <P>SOLUTION: A radio communication device comprises: reception means for receiving first and second signals, where the first and second signals are the same signals received at timing differing from each other and are signals received at the former and latter timing respectively; storage means 11 for storing the first signal; signal detection means 12 for simultaneously receiving the second signal received by the reception means and the fist signal stored by the storage means as input, and outputting a data stream by performing signal separation on the received signals; likelihood extraction means 13 for receiving the first and second signals as input and detecting likelihood information of a channel on the basis of the received signals; multiplication means 14 for multiplying each data stream that is an output signal of the signal detection means by the likelihood information output from the likelihood extraction means as a weight value; and signal demodulation means 15 for obtaining an output signal by demodulating output of the multiplication means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
