WebNov 14, 2024 · This paper proposes two novel schemes of wideband compressive spectrum sensing via block orthogonal matching pursuit (BOMP) algorithm, for achieving high sensing accuracy in real time and demonstrates that the two SC-BOMPs outperform the other benchmark algorithms. This paper proposes two novel schemes of wideband … WebApr 12, 2024 · This study analyzed the mechanical and electrical characteristics of repair self-sensing composites. In order to ensure homogeneous dispersion of carbon nanotubes (CNTs) in the repair mortar, porous powder was impregnated with the liquid MWCNT, dried, and then pulverized. This CNT powder was named S-CNT, and a repair self-sensing … Webof compressed sensing as a tool for image reconstruction. An important application of our work is the problem of MRI. This served as one of the original motivations for compressed sensing, and continues to be a topic of substantial research.
