Timing correcting device and timing correcting method

Abstract

In the timing correcting device, a RAKE path detecting circuitdetects a plurality of path candidates to be tracked, from a reception signal, and outputs a 'timing of a path' and a 'detection correlation value' corresponding to each path candidate, as a result of the detection. Next, each tracking-path candidate deciding circuit (, . . . ) generates a predetermined decision standard that is necessary for selecting an optimum path timing from timings of the path candidates, based on an individually allocated result of the detection. Further, the tracking-path selecting circuitselects a timing of an optimum path to be tracked, based on the result of the detection and the predetermined decision standards. Then, a comparator circuitcompares a predetermined reception reference timing given from the outside with the optimum path timing, and calculates a phase difference between the two. Last, the timing correction control circuitcontrols a clock based on the phase difference, thereby to correct the reception reference timing.
