New Directions In Sparse Sampling and Estimation For Underdetermined Systems [PDF]
, 2013 A central objective in signal processing is to infer meaningful information from a set of measurements or data. While most signal models have an overdetermined structure (the number of unknowns less than the number of equations), traditionally very few ...

Orthogonal phase-frequency coded signal in a pulse against interrupted sampling repeater jamming
The Journal of Engineering, 2019 Interrupted sampling repeater jamming (ISRJ) uses the under sampling technology to transmit and repeat the radar intercepted signals. As a new kind of coherent interference, it is widely used in self-defence interference.

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

Optical signal processing via two-photon absorption in a semiconductor microcavity for the next generation of high-speed optical communications network [PDF]
, 2006 Due to the introduction of new broadband services, individual line data rates are expected to exceed 100 Gb/s in the near future. To operate at these high speeds, new optical signal processing techniques will have to be developed.

Halton Sampling for Image Registration Based on Mutual Information
, 2008 Mutual information is a widely used similarity measure for aligning multimodal medical images. At its core, it relies on the computation of a discrete joint histogram, which itself requires image samples for its estimation.

Joint segmentation of piecewise constant autoregressive processes by using a hierarchical model and a Bayesian sampling approach [PDF]
, 2006 We propose a joint segmentation algorithm for piecewise constant autoregressive (AR) processes recorded by several independent sensors. The algorithm is based on a hierarchical Bayesian model.

Antithetical Stratified Sampling Estimator for Filtering Signals with Discontinuities [PDF]
, 2021 A novel approach to signal filtering using digital alias-free signal processing (DASP) is presented in this paper. We propose an unbiased, fast-converging estimator of the output of a finite impulse response (FIR) continuous-time filter.

Send-On-Delta Concept: An Event-Based Data Reporting Strategy
Sensors, 2006 The paper addresses the issue of the send-on-delta data collecting strategy tocapture information from the environment. Send-on-delta concept is the signal-dependenttemporal sampling scheme, where the sampling is triggered if the signal deviates by ...
