Spectrum sensing is the most crucial part in cognitive radio. The hunger for increased bandwidth requirement has led to explicit research in the field of spectrum sensing techniques. Generalized likelihood ratio test (GLRT) seems to be a technique where energy optimization is possible and hence in this paper we investigated energy detection and GLRT for spectrum sensing for cognitive radio.Our technique shows generalized likelihood ratio test (GLRT) that reduces probability of false alarm versus the probability of detection for different input energy levels.We also carry out simulation with respect to cooperative spectrum sensing to analyze the Probability of Interference.
