Further Results on Performance Analysis for Compressive Sensing Using Expander Graphs [PDF]

open access: yes, 2007
Compressive sensing is an emerging technology which can recover a sparse signal vector of dimension n via a much smaller number of measurements than n. In this paper, we will give further results on the performance bounds of compressive sensing.
