| Description | A bandlimited signal can be reconstructed from its periodic nonuniformly spaced samples provided the average sampling rate is at least the Nyquist rate. Unlike many previously pub-lished methods, the algorithm derived in this paper is de-signed that pays special attention to various practical con-straints. In particular, we propose a fast and numerically ro-bust reconstruction method which can utilize FIR filters with a small number of taps and requires only a modest amount of oversampling to achieve high accuracy. The efficiency and accuracy of the algorithm is obtained by fully exploit-ing the sampling structure combined with utilizing localized Fourier analysis. We discuss applications in time-interleaved analog-to-digital converters where nonuniform periodic sam-pling arises due to timing mismatches. Finally, numerical simulations demonstrate the performance of our algorithm. Index Terms — Signal sampling, Signal reconstruction, Digital filters, Numerical analysis, Numerical stability. |
