On the Compressed Measurements over Finite Fields: Sparse or Dense Sampling
[article]
2012
arXiv
pre-print
Preserved Fulltext
Our results are obtained while the sparseness of the sensing matrices as well as the size of the finite fields are varied. ...
One of interesting conclusions includes that unless the signal is "ultra" sparse, the sensing matrices do not have to be dense. ...
In addition, the numbers of measurements with respect to different sparse factors are obtained. ...
