Abstract

Impairments caused by timing jitter are one of the most important performance limiting factors of digital converters while sampling under Nyquist rates. In this paper, the effect of jitter in such cases is shown and a new method to estimate and reconstruct the timing jitter errors is presented. The system model is based on the estimation of jitter times with an annihilating filter and reconstruction of the signal using Slepian functions without the knowledge of input frequencies. It is shown that, a significant improvement on SNR is achieved.
