Sparse Sampling of Signal Innovations [PDF]
IEEE Signal Processing Magazine, 2008 Sparse sampling of continuous-time sparse signals is addressed. In particular, it is shown that sampling at the rate of innovation is possible, in some sense applying Occam's razor to the sampling of sparse signals. The noisy case is analyzed and solved, proposing methods reaching the optimal performance given by the Cramer-Rao bounds.

Spectrum Aliasing Does Occur Only in Case of Non-ideal Signal Sampling [PDF]
International Journal of Electronics and Telecommunications, 2021 In this paper, it has been shown that the spectrum aliasing and folding effects occur only in the case of non-ideal signal sampling. When the duration of the signal sampling is equal to zero, these effects do not occur at all.

Signal Recovery From Unlabeled Samples [PDF]
IEEE Transactions on Signal Processing, 2017 In this paper, we study the recovery of a signal from a set of noisy linear projections (measurements), when such projections are unlabeled, that is, the correspondence between the measurements and the set of projection vectors (i.e., the rows of the measurement matrix) is not known a priori.

Modelling of Non-ideal Signal Sampling via Averaging Operation and Spectrum of Sampled Signal Predicted by this Model [PDF]
TransNav, 2022 In this paper, a novel model of a non-ideal signal sampling via a local, periodic averaging operation is present-ed. The spectrum of a sampled signal predicted by this model is also analysed as well as compared with a one following from another model.

The extraction of the new components from electrogastrogram (EGG), using both adaptive filtering and electrocardiographic (ECG) derived respiration signal [PDF]
, 2015 Electrogastrographic examination (EGG) is a noninvasive method for an investigation of a stomach slow wave propagation. The typical range of frequency for EGG signal is from 0.015 to 0.15 Hz or (0.015–0.3 Hz) and the signal usually is captured with ...

Optically Enabled ADCs and Application to Optical Communications
IEEE Open Journal of the Solid-State Circuits Society, 2021 Electrical-optical signal processing has been shown to be a promising path to overcome the limitations of state-of-the-art all-electrical data converters. In addition to ultra-broadband signal processing, it allows leveraging ultra-low jitter mode-locked

Sampling of graph signals via randomized local aggregations [PDF]
, 2019 Sampling of signals defined over the nodes of a graph is one of the crucial problems in graph signal processing. While in classical signal processing sampling is a well defined operation, when we consider a graph signal many new challenges arise and ...
