Abstract:

This report presents, for the first time, the exact theoretical solution to the problem of maximum-likelihood ML estimation of time-varying delay, dt, between a random signal, st, received at one point in the presence of uncorrelated noise and the time-delayed, scaled version ast - dt of that signal received at another point nonstationary Gaussian random process and the observation interval is arbitrary.
