abstract = {The Gershgorin radii and centers ratio (GRCR) and the Gini index detector (GID) test statistics have been recently proposed as, blind, simple and robust solutions for centralized cooperative spectrum sensing under non-uniform and dynamical received signal and noise powers. In this paper, an hybridization of these test statistics is proposed, which is named hybrid GRCR-GID (HGG). It is demonstrated that the HGG harvests the advantages of the base detectors, attaining approximately the same performance of the GRCR in the absence of a dominant propagation path, and a little inferior performance with respect to the GID in the presence of dominant path. Moreover, the HGG is capable of outperforming the GRCR and the GID in some system configurations, maintaining robustness, low computational complexity, and the constant false alarm rate property.},
