In order to overcome this problem, it is necessary to use the existing frequency spectrum in the most efficient way. Cognitive radio systems are the emerging technologies to solve these problems. The first step in cognitive radio systems is the detection of the full / empty state of the current spectrum. Blind methods for this detection are highly preferred in terms of ease of implementation and computational cost. In this study, performance analyzes of Rayleigh, nakagami-m, nakagamin and nakagami-q fading communication channels of blind spectrum detection methods are performed. A MIMO-OFDM based communication system was used in the study. Simulations were performed in MATLAB environment.
