<P>PROBLEM TO BE SOLVED: To provide a W-CDMA device for improving reception characteristics even when only one path is detected. <P>SOLUTION: A searcher part 11 calculates a path delay amount by performing correlation calculation from a reception base band signal, and notifies finger parts 14-1 to 14-n of the path delay amount under the consideration of the influence of the adjacent path. That is, when notifying the finger parts 14-1 to 14-n of path information, the searcher part 11 notifies the finger parts 14-1 to 14-n of the plurality of pieces of path information when there is a possibile adjacent path. The finger parts 14-1 to 14-n perform inverse diffusion, channel estimation and synchronous detection on the basis of the path information notified from the searcher part 11, and perform RAKE composition to all the paths. <P>COPYRIGHT: (C)2009,JPO&INPIT |
