In this paper, author consider
cooperative spectrum sensing in order to optimize the sensing
performance and focus on energy detection for spectrum sensing
and find that the optimal fusion rule is the half-voting rule.
Next, the optimal detec

These
cooperations are facilitated by dynamically and opportunistically assigning one of the secondary users as a relay to assist the other
one, which results in more efficient spectrum hole detection. Also, we investigate the impact of erroneous

In this paper, we analyze the performance of
spectrum sensing based on energy detection. We do not assume
the exact noise variance is known a priori. Instead, an estimated
noise variance is used to calculate the threshold used in the
spectrum

In this paper we uate the performance of cooperative spectrum sensing (CSS) where
each cognitive radio (CR) employs an improved energy detector (IED) with multiple antennas and
uses selection combining (SC) for detecting the primary user (PU) in
