Nonuniform sampling and its reconstruction methodologies
MetadataShow full item record
Alias-free DSP (DASP) is a methodology of processing signals digitally inside bandwidth that are wider than the famous nyquist limit of half of the sampling frequency. This topic has benefited from a strong research revival during the past few years. DASP is facilitated by suitable combination of non-uniform sampling and appropriate processing algorithms. In this thesis different stretegies to perform nonuniform sampling and its spectrum analysis are studied. We examine the problem of reconstructing a signal from non-uniform samples. A polynomial interpolation based reconstuction techniques are presented. Its performance are compared with the other previous papers on reconstruction technique on the basis of MSE criteria and Complexity of algorithm.
