<p>PROBLEM TO BE SOLVED: To easily improve the accuracy of maximum correlation detection without changing a sampling rate. SOLUTION: A maximum correlation detecting position correction section 5 is an especially important section in this invention, receives a correlation from a correlation device 4, corrects a timewise position of a most probable maximum correlation depending on the relation of quantity among three correlation values being the maximum correlation and two correlation values before and after the maximum correlation value when receiving two kinds of maximum correlation discrimination threshold signalsθ1,θ2 from a control section 2A to detect the position of the maximum correlation value and informs the result to the control section 2A.</p> |
