چکیده
|
Compressive sensing (cs) reconstruction of a spectrum-sparse signal from undersampled data is,in fact,an ill-posed problem. in this paper,we mathematically prove that,in certain cases,the exact cs reconstruction of a spectrum-sparse signal from undersampled data is impossible. then we present the exact cs reconstruction condition of undersampled spectrum-sparse signals,which is valuable for digital signal compression. © 2013 ying luo et al.
