Performance Evaluation of Blind Spectrum Detection Methods for 34 Different Communication Channels in Cognitive Radio Systems

Abstract

In today's wireless communication systems, the problem of spectrum shortage has emerged with the increase of service standard. In order to overcome this problem, it is necessary to use the existing frequency spectrum most efficiently. Cognitive radio technologies are defined as the whole of the emerging technologies in order 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 perception are the reason for much preference in terms of ease of implementation and cost of calculation. In this study, performance analyzes of different communication channels of blind spectrum detection methods are performed. A randomly generated zero-mean primary user and noise signals are used in the study. Spectrum sensing was performed using the eigenvalues of the covariance matrices of the signals received by the multiple antennas. The generalized likelihood ratio  detection is based on the detection probability limit value allowed by the international communication committee. Simulations were performed in MATLAB environment. As it is known, the channel that fully models the wireless 802.11 communication channel is the Weibull fading channel. Looking at the simulation results, it is seen that the best detection performance for the eigenvector detection is in the Rayleigh fading channel. However, weibull channel results should be taken into account when real applications do not fully accommodate rayleigh channel wireless channels. Moreover, according to the simulation results, the detection performance for the nakagami-m damped channel was found to be the most unsuccessful.
