Abstract: <P>PROBLEM TO BE SOLVED: To provide a diversity receiver of reception quality higher than before or a diversity receiver which is relatively inexpensive and small-sized considering the reception quality.  <P>SOLUTION: A compositing device 304 equivalent to the incoming wave generation part 2 of a second means composites reception waves X<SB>1n</SB>(1≤n≤N) by using a complex weighting factor W<SB>2n</SB>(1≤n≤N) supplied from a secondary incoming wave estimation part 303 and thus generates virtual incoming waves Yv. Since signals (reception waves X<SB>1n</SB>) inputted to the compositing device 304 are not passed through a secondary component extraction part 302, the virtual incoming waves Yv are generated without being weakened specially in the middle. The virtual incoming waves Yv do not match the delayed waves (secondary incoming waves Y<SB>2</SB>) however sufficiently contain the spectrum components of the delayed waves and a reception level (strength) is maintained high without being weakened specially. Thus, frequency spectrum synthesis is effectively carried out even in the case that the incoming directions of primary incoming waves Y<SB>1</SB>and the secondary incoming waves Y<SB>2</SB>are close.  <P>COPYRIGHT: (C)2004,JPO
