TamaRISC-CS: An ultra-low-power application-specific processor for compressed sensing [PDF]
2012 IEEE/IFIP 20th International Conference on VLSI and System-on-Chip (VLSI-SoC), 2012 Compressed sensing (CS) is a universal technique for the compression of sparse signals. CS has been widely used in sensing platforms where portable, autonomous devices have to operate for long periods of time with limited energy resources. Therefore, an ultra-low-power (ULP) CS implementation is vital for these kind of energy-limited systems.

A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]
, 2010 Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of

Single-Sensor Vibration Sensing in Anisotropic Composites Enabled by Disordered Metasurfaces. [PDF]
Adv Sci (Weinh)This work develops a single‐sensor vibration sensing (SSVS) framework that integrates disordered metasurfaces with compressive sensing. Comprehensive numerical and experimental validations demonstrate that, by manipulating anisotropic guided wave propagation through metasurfaces, the proposed SSVS framework enables high‐fidelity multi‐source vibration ...
