摘要：

This paper deals with the results on the reconstruction accuracy of the irregularly sampled discrete-time signal (DTS) with unknown sampling locations. Reconstruction is performed by means of special reconstruction algorithms based on the sampling locations estimation. Comparison is done for results of estimation of the algorithms accuracy and accuracy of signal reconstruction by means of interpolation using the fast Fourier transform (FFT). The results show that the accuracy of the studied model DTS reconstruction when using proposed algorithms appear to be higher under the uniform distribution law of jitter as well as for the normal one.
