Abstract
We present some forms of uncertainty principle which involve in a new way localization operators, the concept of ε-concentration and the standard deviation of L2 functions. We show how our results improve the classical Donoho-Stark estimate in two different aspects: a better general lower bound and a lower bound in dependence on the signal itself.
