The The sampling blocksampling block constructs a constructs a matrix Amatrix A that operates on the signal: that operates on the signal: y(t)=Ax(t) y(t)=Ax(t)
The The reconstruction blockreconstruction block - - Reconstructs the Reconstructs the support Ssupport S of x out of A of x out of A
and y.and y. Now, Using Now, Using SS, we invert , we invert AA and and
reconstruct Xreconstruct X.. The algorithm was successfully The algorithm was successfully
simulated in Matlab.simulated in Matlab.
Our MissionOur Mission Implement Implement the reconstruction the reconstruction
algorithm by software (C++) algorithm by software (C++) with hardware orientation.with hardware orientation.
