Abstract :
A nonuniform compressive sampling digital signal processing method and its application in the frequency detection studied in this paper. The fundamental principle of nonuniform compressive sampling is explored, the nonuniform compressive sampling has being able to suppress the aliasing. The experiences demonstrated this method can detect the signal frequency by low analog digital conversion at sub-Nyquist rates.
