Estimation of signal and noise spectra by special averaging techniques with application to a posteriori "Wiener" filtering.

abstract：:We present a procedure that optimally adjusts specified parameters of a mathematical model to describe a set of measured data. The technique integrates a dynamic systems-simulation language with a robust algorithm for nonlinear parameter estimation, and it can be implemented on a microcomputer. Sensitivity functions a...
