<P>PROBLEM TO BE SOLVED: To provide an OFDM receiver for obtaining a reception signal whose quality is satisfactory at the time of diversity-receiving an OFDM signal. <P>SOLUTION: This OFDM receiver is provided with a propagation path estimating part 108 for estimating propagation path characteristics in the frequency region of each antenna branch on the basis of the FFT output signals of respective antenna branch processing units BR-1 to BR-N, a signal quality estimating part 109 for estimating the signal quality of each antenna branch on the basis of the output signal of the propagation path estimating part 108, a multiplying part 110 for multiplying the propagation path characteristics and the signal quality by corresponding branches, and a composition part 107 for performing weighting composition of the FFT output signals on the basis of the multiplication result. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
