Optimum Estimation of the Moment of Emergence of a Signal in the Presence of Multiplicative High-frequency Gaussian Noise
V. A. Volkonskii Moscow
Abstract:
A process
$\xi_\lambda(t)$ of the form (2) is observed, where
$S(t-\tau)$ is a signal of a well-known form, which depends on an unknown parameter
$\tau$;
$\nu(t)$ is Gaussian noise with a spectral density as in (1a). The problem is to detect a class of estimations of the parameter
$\tau$, whose exactness does not vary when the process
$\xi_\lambda(t)$ changes somewhat. A class of processes
$\tilde{\xi}_\lambda(t)$ approximating the process
$\xi_\lambda(t)$ is determined by means of relation (3). A class of estimations
$\tilde\tau$, whose exactness is the same for all processes
$\tilde\xi_\lambda$ approximating the process
$\xi_\lambda$, is determined from (4). An optimum estimation for this class is found.
