摘要：
Spectra estimation of irregularly sampled signals is an important issue in time series analysis. To improve spectral resolution of irregular sampling signals, this paper presents a suppression algorithm of frequency spectrum leakage for non-uniform Discrete Fourier Transform (NDFT). The DFT computation of irregularly sampled signals is performed via iterative non-linear estimation. Actual computing results show that the approach can effectively suppress frequency spectrum leakage in NDFT results, improve the resolution of DFT spectra.
