Reliable detection of the existence of primary users is a primary requirement for the minimization of interference to existing primary networks. Cognitive radio (CR) systems need to detect the presence of licensed primary user (PU) reliably. Spectrum sensing is one of the systems which checks the vacancy of primary user designated to particular frequency spectrum. Cooperation among multiple CRs helps to enhance the reliability of detection of the PU in case of unreliable decision by a single CR… Expand
