In this paper, we study the eigen decomposition method of high resolution frequency estimation of sinusoidal signal from the perspective of amending covariance matrix, reveal the mechanism of eigen decomposition method of noise impact and some typical principles of eigen decomposition to suppress noise interference, and get four meaningful conclusions Through a large number of computer simulation experiments to study the performance of the main characteristic decomposition method, and further verify the conclusions obtained.
