We show that the quality of signal reconstruction can be significantly enhanced by the introduction of a linear chirp modulation, which induces a spread spectrum phenomenon.Image processingcompressed sensingradio interferometrymagnetic resonance imagingLTS2LTS5MIPLabCIBM-SPCCIBM-AITtext::conference output::conference proceedings::conference paper
