In this paper, we consider a hybrid framework combining compressive spectrum sensing with geo-location database to find the spectrum holes in cognitive radio. In the hybrid framework, a geo-location database algorithm is proposed to be stored locally at secondary users (SUs) to remove the extra transmission link to a centralized remote geo-location database. Specifically, by utilizing the output of geo-location database algorithm, a data-assisted non-iteratively reweighted least squares (DNRLS)doi:10.1109/twc.2015.2485992 fatcat:oeqxeydgs5avrai2jk6qa5vleq
