Sub-Nyquist artefacts and sampling moiré effects [PDF]
Royal Society Open Science, 2015 Sampling moiré effects are well known in signal processing. They occur when a continuous periodic signal g(x) is sampled using a sampling frequency fs that does not respect the Nyquist condition, and the signal-frequency f folds over and gives a new ...

Sub-Nyquist SAR Based on Pseudo-Random Time-Space Modulation [PDF]
Sensors, 2018 Sub-Nyquist sampling technology can ease the conflict between high resolution and wide swath in a synthetic aperture radar (SAR) system. However, the existing sub-Nyquist SAR imposes a constraint on the type of the observed scene and can only reconstruct

Sub‐Nyquist receiver using sampling frequency and instant offsets
The Journal of Engineering, 2021 With rapid advance in analogue‐to‐digital converters, more analogue‐to‐digital converters in the market can cover multiple Nyquist zones. As a result, the implementation of a sub‐Nyquist receiver designed to cover a bandwidth wider than what is dictated ...

A hardware prototype of sub‐Nyquist radar with unknown pulses
Electronics Letters, 2021 In a conventional radar system, the hardware cost increases with the sampling rate of the receiver. Sub‐Nyquist radar systems operate at lower sampling rates and hence reduce the hardware cost and complexity. A sub‐Nyquist radar system uses the knowledge

Wideband spectrum sensing based on advanced sub-Nyquist sampling structure
EURASIP Journal on Advances in Signal Processing, 2022 As the bandwidth increases, the high-speed sampling rate becomes the bottleneck for the development of wideband spectrum sensing. Wideband spectrum sensing with sub-Nyquist sampling attracts more attention and modulated wideband converter (MWC) is an ...
