Optimized Statistical Beamforming for Cooperative Spectrum Sensing in Cognitive Radio Networks
In cognitive radio (CR), cooperative spectrum sensing (CSS) employs a fusion of multiple decisions from various secondary user (SU) nodes at a central fusion center (FC) to detect spectral holes not utilized by the primary user (PU).The energy detector (ED) is a well-established technique of spectrum sensing (SS).However, a major challenge in desig
