## Abstract We show that the recently discovered WILSON bases of exponential decay are unconditional bases for all modulation spaces on __R__, including the classical BESSEL potential spaces, the Segal algebra __S__~o~, and the SCHWARTZ space. As a consequence we obtain new bases for spaces of enti
## Abstract The __á__ ‐modulation spaces are a family of spaces that contain the Besov and modulation spaces as special cases. In this paper we prove that brushlet bases can be constructed to form unconditional and even greedy bases for the __α__ ‐modulation spaces. We study __m__ ‐term nonlinear a
