Compressive Sensing - RWTH Aachen University

WebbCompressive sensing (CS) or compressive sampling is an emerging technique for acquiring and reconstructing a digital signal with potential benefits in many applications. The CS method takes advantage of a sparse signal in a specific domain to significantly reduce the number of samples needed to reconstruct the signal [1]. Webb8 sep. 2024 · Compression sensing is a new signal acquisition theory, which breaks through the limitation of Nyquist sampling theorem. The sampling frequency of compressed sensing signal is determined by the structure and content of the signal, and the coding and decoding frame of compressed sensing signal is asymmetric. opus technology logoWebbA method of spectral sensing based on compressive sensing is shown to have the potential to achieve high resolution in a compact device size.
