Cons and Pros of Compressed Sensing

Y= AX;

Cons:

For noise in y (measurement noise), CS only wildly amplify the noise;

For noise in x which is usually the case, the SNR decrease 3dB when undersampling ratio doubles (N/M);

Pros:

Dynamic range gain is theoretically 7.9dB for each doubling in N/M
