GHz sampling hardware implementation with sub-Nyquist coprime sampling rates

Review of Scientific Instruments, 2019
A sub-Nyquist coprime sampling system for sparse signals is implemented in this article. The proposed system is composed of coprime sampling hardware and a multicoset signal reconstruction algorithm. A pair of uniform samplers is utilized in the hardware to sample a wideband spare analog signal with an uncertain difference in start times.

Speed-enhanced scattering compensation method with sub-Nyquist sampling

Optics Letters
A rapid feedback-based scattering compensation method is particularly important for guiding light precisely within turbid tissues, especially the dynamic tissues. However, the huge number of measurements that come from the underutilization of the signal frequency channel greatly limits the modulation speed.
