  • Compressive Sensing Lecture Notes IEEE Journals

    Compressive Sensing Lecture Notes Abstract This lecture note presents a new method to capture and represent compressible signals at a rate significantly below the Nyquist rate. This method called compressive sensing employs nonadaptive linear projections that preserve the structure of the signal the signal is then reconstructed from these
