Abstract :
We propose novel detectors for cooperative spectrum sensing in mixture-Nakagami fading channels, namely 1) the Neyman-Pearson Detector (NPD), 2) a Locally Optimum Detector for weak signals that exploit the correlation between the observations and transmitted signals, 3) a weak signal detector for unknown parameters and 4) two Generalized-Likelihood-Ratio detectors (GLRDs) that exploit the received energies. They significantly outperform energy and cyclostationary detectors in practical scenarios. We also analyze the performance of the NPD and GLRD for unknown transmitted signal over Rayleigh channels, where they reduce to a linear weighted-correlator and a weighted-energy detector respectively.
