Abstract :
In this paper, we propose a time-domain method for uniform signal reconstruction from periodic nonuniform samples of a bandlimited signal when timing-skews are known. The algorithm computes a constrained least-squares estimate of the input via the pseudoinverse of a time-varying filter. The method exploits the oversampling in the system to provide increased performance in the presence of noise.
