Study on nonuniform sampling signals based on wavelet transform
Xiangping Cai, Dong Li, An Min Wang · 2010
A nonuniform sampling digital signal processing method based on wavelet transform and its application in the frequency detection studied in this paper. The fundamental principle of nonuniform sampling wavelet transform is explored, and the processing procedure is illustrated from the uniform wavelet to nonuniform wavelet. The experimental results demonstrated that the wavelet transform based nonuniform sampling was effective in signal detecting digital signal processes, and accurate in estimating the frequencies of sinusoidal signals.
