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 DTS values correction. The first algorithm is drawn on applying of the non-recursive smoothing filter (NRSF). The second algorithm is based on the local least squares signal approximation. Its accuracy is validated in the numerical examples. The proposed algorithms were compared to the several interpolation methods, one's using digital lowpass filter and the fast Fourier transform (FFT), by the reconstruction error.
