a. Follow-ups to Session 13 • Comment on the codes from Session 13. The codes used in Session 13 use various " tricks " or shortcuts to make them more compact. In general, I don't recommend coding this way (so these codes should be rewritten!). For example, the choice of energy units is exploited so that energies are integers and therefore can be used as array indices. But if we added an extern...

the focus of this paper is to consider the compressed sensing problem. it is stated that the compressed sensing theory, under certain conditions, helps relax the nyquist sampling theory and takes smaller samples. one of the important tasks in this theory is to carefully design measurement matrix (sampling operator). most existing methods in the literature attempt to optimize a randomly initiali...
