In the timing correcting device, a RAKE path detecting circuit 1 detects 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 ( 2 a , 2 b , 2 c, . . . ) 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 circuit 3 selects a timing of an optimum path to be tracked, based on the result of the detection and the predetermined decision standards. Then, a comparator circuit 5 compares 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 circuit 6 controls a clock based on the phase difference, thereby to correct the reception reference timing.
