Patent ID: 7412014

Claim:
A timing adjusting apparatus, comprising: a sampling unit which samples respectively a plurality of received signals at predetermined timings; a correlation processing unit which performs a correlation processing respectively on the plurality of sampled received signals by predetermined signals; a power computing unit which respectively computes power values of a main signal and sub-signals where one of the plurality of correlation-processed received signals is selected as the main signal and signals other than the main signal among the plurality of correlation-processed signals are the sub-signals; a detector which detects respectively a peak of the computed power value of the main signal and a peak of the computed power value of the sub-signals; an acquiring unit which acquires power values respectively corresponding to before and after the timing of the detected peak of the detected power value of the main signal, and which acquires power values respectively corresponding to before and after the timing of the detected peak of the power value of the sub-signals; a derivation unit which derives, based on the respective power values acquired by said acquiring unit, a first value indicating the degree of agreement between timings of the main signal and the sub-signals and a second value indicating the degree of variance between the timings of the main signal and the sub-signals; and a shift unit which shifts timing of received signals corresponding to the sub-signals, among the plurality of sampled received signals, based on the second value derived by said derivation unit if the derived second value is greater than the derived first value.
