Method and apparatus for compressed sensing using analog projection Patent uri icon


  • Embodiments of the present invention provide a method and apparatus for compressed sensing. In some embodiments, the apparatus (10) generally includes a receiving element (12) operable to receive an input signal, an integrate/dump circuit (14), a sampling element (16), and a processor (18). The integrate/dump circuit (14) is operable to integrate at least a portion of the received signal to provide an integrated signal and the sampling element (16) is operable to sample the integrated signal at a first sampling rate which is less than the Nyquist rate for the input signal. The processor (18) is operable to form a compressed sensing matrix utilizing a first set of time indices corresponding to the first sampling rate, form a measurement vector utilizing at least a portion of the sampled signal, and reconstruct at least a portion of the input signal utilizing the compressed sensing matrix and the measurement vector.
