现代频谱估计是非线性估计，在20世纪70年代后发展起来，具有较高的频率分辨率-Modern spectrum estimation is a nonlinear estimation, developed in the 1970s, has a higher frequency Resolution.

Modern signal processing used in the spectral estimation in matlab, Rotating Machinery dimensional hologram of practical spectrum calculation routines, Signal dimension estimates.

University of numerical analysis algorithms, Modern signal processing jobs when the graduate, Based on the time delay estimation of power spectrum.
