Interpretation of Spectral Estimation Results for Nonstationary Signals
S. Yu. Pliskin, V. A. Karpenko · COMPSTAT · 1990
We consider application of spectral estimation methods (MSE) to the problem of identification of parameters of nonstationary signals. The main result of our work is obtaining interpretation conditions, that take into account frequency resolution and nonstationarity of different components of the signal at the same time. These conditions establish the connection between the length of stationarity intervals and a priori information about signal parameters.
