Claim Text:
1. A diversity reception device that receives a signal that has been digitally modulated by single carrier modulation, comprising: a plurality of branch processing units to each of which one of a plurality of received signals is individually inputted; a combination and equalization unit calculating an equalized signal from said plurality of received signals; and a transmitted symbol estimation unit calculating an estimated transmitted symbol from said equalized signal; wherein each of said branch processing units comprises: a front end unit performing processes including modulation frequency conversion upon said received signal that has been inputted thereto, thus converting it to a baseband signal; a channel frequency characteristic estimation unit calculating an estimated channel frequency characteristic on the basis of said baseband signal and said estimated transmitted symbol; and a carrier frequency control unit controlling the conversion frequency for said modulation frequency conversion on the basis of said estimated channel frequency characteristic.
