Patent ID: 7345603

Claim:
An apparatus for reconstructing an input signal, the apparatus comprising: a receiving element operable to receive the input signal; an integrate/dump circuit coupled with the receiving element, the integrate/dump circuit operable to integrate at least a portion of the received signal to provide an integrated signal and dump the integrated portion of the received signal, a sampling element coupled with the integrate/dump circuit, the sampling element operable to receive the integrated signal and sample the integrated signal at a first sampling rate to provide a sampled signal, the first sampling rate being less than the Nyquist rate for the input signal; and a processor coupled with the sampling element, the processor operable to form a compressed sensing matrix utilizing a first set of time indices corresponding to the first sampling rate, receive at least a portion of the sampled signal, 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.
