Rate distortion performance analysis of nested sampling and coprime sampling
In this paper, rate distortion performance of nested sampling and coprime sampling is studied. It is shown that with the increasing of distortion, the data rate decreases. With these two sparse sampling algorithms, the data rate is proved to be much less than that without sparse sampling. With the increasing of sampling spacings, the data rate decreases at certain distortion, which is because w...

Title of Thesis: Performance and Robustness Analysis of Co-Prime and Nested Sampling Ali Koochakzadeh, Master of Science, 2016 Thesis Directed By: Professor Piya Pal Department of Electrical and Computer Engineering Coprime and nested sampling are well known deterministic sampling techniques that operate at rates significantly lower than the Nyquist rate, and yet allow perfect reconstruction of...
متن کاملRate-distortion optimization for compressive video sampling
The recently introduced compressed sensing (CS) framework enables low complexity video acquisition via subNyquist rate sampling. In practice, the resulting CS samples are quantized and indexed by finitely many bits (bit-depth) for transmission. In applications where the bit-budget for video transmission is constrained, ratedistortion optimization (RDO) is essential for quality video reconstruct...
متن کاملProperties of nested sampling
SUMMARY Nested sampling is a simulation method for approximating marginal likelihoods proposed by Skilling (2006). We establish that nested sampling has an approximation error that vanishes at the standard Monte Carlo rate and that this error is asymptotically Gaussian. We show that the asymptotic variance of the nested sampling approximation typically grows linearly with the dimension of the p...
متن کاملDistortion and Noise Performance of Bottom-Plate Sampling Mixers
Wei Yu, Bosco Leung, Senior Member, IEEE Department of Electrical and Computer Engineering, University of Waterloo, Waterloo, Ontario, Canada N2L 3G1 Abstract| Distortion and noise due in a bottom-plate sampling mixer is analyzed. The method of Volterra series is applied in the analysis of harmonic distortion, which combines the e ects of continuous time, time varying, and sampling distortions....
