| Abstract: | Power Spectral Estimation have an important function in modem signal processing. This paper selects two classic statistical signal processing algorithms MVDR and MUSIC as object of study, introduces radical principle of two algorithms, gives realizable method of it based on MATLAB, and proves availability of it in noise - signal detection. Finally, it draws a important conclusion by stimulation that MUSIC algorithm more higher resolution performance than MVDR algorithm in noise - signal detection. |
