Information-Theoretically Optimal Compressed Sensing via Spatial Coupling and Approximate Message Passing
Compressed sensing random sensing matrix the space coupling space coupling
2015/8/21
We study the compressed sensing reconstruction problem for a broad class of random, banddiagonal sensing matrices. This construction is inspired by the idea of spatial coupling in coding theory. As de...
