PROBLEM TO BE SOLVED: To make the power consumption of a matched filter low. SOLUTION: For correlation detection of oversampling data, a plurality of shift registers (100, 200) are provided in parallel corresponding to multiples of oversampling, respective shift states are controlled by the shift registers by using a shift control signal (SEL) and a shift clock (CLK etc.), and the shift control signal (SEL) and shift clock are used to associatively switch selectors (30a to 30n) of a data selection part 300. |
