<p>PROBLEM TO BE SOLVED: To prevent the omission of data at the switching time of path allocation. SOLUTION: In this rake receiver provided with plural fingers 111-113 for applying inverse spreading processing to the desired signal coming via the allocated path among multi-path and outputting an inverse spreading signal provided by the inverse spreading processing while adding a delay amount corresponding to this path, combining part 12 for combining the outputs of the respective finger parts and path search part 13 for allocating the path to each finger part, at the path search part 13, a correlation detecting part 31 detects the correlation of received wave and desired wave and outputs a correlation value and correlation detecting time, a path selecting part 33 selects the path, through which the desired signal to apply inverse spreading comes, based on the correlation value, a path follow-up part 34 decides whether, or not the selected path is equal with a path allocated to each finger part up to the moment, based on the detection timing of the correlation value. When it is the same path, the finger part of the same up to the moment executes inverse spreading and delay control processing with respect to the desired signal coming through the selected path.</p> |
