PROBLEM TO BE SOLVED: To efficiently estimate a propagation delay time with less throughput and small-scale hardware.;SOLUTION: The propagation delay time estimator for estimating a propagation delay time showing a difference between two kinds of discrete time signals initially the same comprises: first and second binary encoding means for converting discrete time signals X(n) and Y(n) into one-bit signals Xbin(n) and Ybin(n) according to being less than, equal to, or more than the mean value of their dynamic ranges; a correlation operating means for operating a mutual correlation between the one-bit signals Xbin(n) and Ybin(n); and a propagation delay time estimating means for estimating the propagation delay time on the basis of a time difference k giving the maximum value between mutual correlation coefficients Corr(n, k) within the range of 0≤k≤M.;COPYRIGHT: (C)2008,JPO&INPIT
