Annotations languages:

The problem of efficiency enhancing of spectral analysis of the signals observed on the noise background via ESPRIT with data preprocessing by SSA method (by modification of the method) is considered in the paper. The simulations results are presented that confirm the enhancement of spectral analysis efficiency by ESPRIT method when using the SSA method and its modification.
Keywords: noise reduction in observation, eigenvalues, eigenvectors, singular values, singular vectors, small samples, ESPRIT, SSA method, segment size
