Cooperative Spectrum Sensing Using Hard Decision Fusion Scheme

Abstract—Cooperative spectrum sensing using energy detection is the efficient method of detecting the spectrum holes in a particular band of interest or channel by combining the information gathered by multiple CR users. In this paper, we study the hard decision fusion scheme using Logical ‗AND ‘ and the Logical ‗OR ‘ rule and a brief introduction of Soft and Quantized fusion scheme. Simulation compares ROC (Receiver Operating Characteristics) curves for the above mentioned scheme. And it shows that the Logical ‗OR ‘ has better performance than the Logical ‗AND ‘ rule
