Patent ID: 7443934

Claim:
A signal detecting apparatus, comprising: a sampling unit which samples respectively a plurality of symbols contained in a signal to be received, at an interval less than or equal to that of a symbol; a correlation unit which generates respectively a plurality of correlation values by performing correlation processing on the plurality of symbols sampled by said sampling unit; a statistical processing unit which associates respectively the plurality of correlation values to timings to be sampled included in an interval of one symbol, and performs statistical processing over the plurality of symbols on the plurality of associated correlation values at the respective timings; a selector which selects a maximum value from among the plurality of correlation values on which the statistical processing has been performed at the respective timings; an averaging unit which performs averaging processing on the plurality of correlation values on which the statistical processing has been performed at the respective timings; and a detector which determines detection of the signal to be received, based on the maximum value selected by said selector and the average correlation value on which the averaging processing has been performed.
