A Sub-Nyquist Radar Electronic Surveillance System [PDF]
IEEE Access, 2018 The modulated wideband converter (MWC) is well-known for a sub-Nyquist wideband sampling capability based on compressed sensing (CS) theory. In this paper, our goal is to use the MWC as a base to design a sub-Nyquist radar electronic surveillance (ES ...

High-speed, sub-Nyquist interferometry [PDF]
Optics Express, 2011 The velocity measurement limit in dynamic interferometry is vNyq, the velocity at which the interferogram is sampled at the Nyquist limit. We show that vNyq can be exceeded by assuming continuity of the surface motion and unwrapping the velocity modulo 2vNyq.

Sub-Nyquist Sampling OFDM Radar [PDF]
IEEE Transactions on Radar Systems, 2023 In this paper, we propose a sub-Nyquist sampling (SNS) orthogonal frequency-division multiplexing (OFDM) radar system capable of reducing the analog-to-digital converter (ADC) sampling rate in OFDM radar without any additional manipulations of its hardware and waveform.

Compressive Detection Using Sub-Nyquist Radars for Sparse Signals
International Journal of Antennas and Propagation, 2016 This paper investigates the compression detection problem using sub-Nyquist radars, which is well suited to the scenario of high bandwidths in real-time processing because it would significantly reduce the computational burden and save power consumption ...

Spike sorting at sub-Nyquist rates [PDF]
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012 Spike sorting relies on the ability to establish the temporal occurrence of action potentials and their relation to specific neurons. Neural information is intrinsically compressible and as such suitable for sparse sampling. Potentially, this should allow for the use of multi-channel recordings, which is particularly advantageous to improve spike ...
