We consider multi-antenna cooperative spectrum sensing in cognitive radio networks, when there may be multiple primary users. A detector based on the spherical test is analyzed in such a scenario. Based on the moments of the distributions involved, simple and accurate analytical formulae for the key performance metrics of the detector are derived. The false(More)
—We consider an adaptive co-primary spectrum sharing scheme based on playing one-shot games between co-located distributed Radio Access Networks (RANs). Spectrum is divided into private and shared parts, and each RAN internally applies coordinated multi-point transmissions. Zero-forcing precoding is used in the private part, while unitary precoding is(More)
