The influence of estimate of observation noise variance on the effectiveness of signal preprocessing by modified SSA method is analyzed in the paper. It is showed that using the noise variance estimate obtained with application of general statistical analysis results allows to improve the performance of spectral analysis when using signal preprocessing by modified SSA method.
