Iterative Hard Thresholding for Compressed Sensing
Compressed sensing is a technique to sample compressible signals below the Nyquist rate, whilst still allowing near optimal reconstruction of the signal. In this paper we present ...

Compressed sensing radar
A stylized compressed sensing radar is proposed in which the timefrequency plane is discretized into an N × N grid. Assuming the number of targets K is small (i.e., K N2 ), then ...

On The Empirical Rate-distortion Performance Of Compressive Sensing
Compressive Sensing (CS) is a new paradigm in signal acquisition and compression. In compressive sensing, a compressible signal is acquired using much less measurements than the o...
