Robustly Stable Signal Recovery in Compressed Sensing with Structured Matrix Perturbation
Zai Yang, Cishen Zhang, Lihua Xie
The sparse signal recovery in the standard compressed sensing (CS) problem requires that the sensing matrix be known a priori. Such an ideal assumption may not be met in practical…

On Phase Transition of Compressed Sensing in the Complex Domain
Zai Yang, Cishen Zhang, Lihua Xie
The phase transition is a performance measure of the sparsity-undersampling tradeoff in compressed sensing (CS). This letter reports our first observation and evaluation of an empi…
