Abstract :
Among other applications, being an existing
technology cognitive radio has the potentiality to
unlock the spectrum which is needed to bring it
into effective action for the next generation of
high data rate systems. Infarct, in cognitive
radio technology spectrum sensing is a basic
component. However, if the users feel fading
effect, in that matter detection can be
compromised. The result of misdirection is that
the user cannot be able to discern between an
unused band and a deep fade. That is why, to
optimize cooperative performance the proposed
term is spectrum sensing. The performance of
cooperative spectrum sensing is also analyzed by
us. In this session the main focus of this paper is
to simulate comparison of cooperative with the
non-cooperative spectrum sensing about the
Rayleigh fading channel based on OR and AND
majority rule. It is noticeable that in the
presence of cooperation the spectral sensing
presence is better by comparing the
noncooperation curve with the cooperative
curves compared to the Rayleigh fading
channel. Additionally, it is also noticeable that
the performance of the AND and other majority
rules is not as good as OR rule.
