Spectrum sensing is one of the critical aspects in cognitive radio (CR). CR user must be able
to detect the spectrum opportunity reliably and efficiently in order to use the available …

Cognitive radio (CR) technology has been proposed to improve spectrum utilization by
allowing cognitive radio users to opportunistically access under-utilized frequency band …

Recently, cognitive radio (CR) access has received much attention to overcome spectrum
scarcity problem. Spectrum sensing methods are often used for finding free channels to be …

This paper proposes a cooperative spectrum sensing algorithm based on distributed fusion
strategy and maintained probability of false alarm for cognitive radio. It further introduces a …

Cooperative spectrum sensing is used to overcome limited computing power of individual
nodes to correctly estimate existence of primary user in presence of multipath fading …

Increased demand of wireless spectrum in current wireless environment needs the proper
utilization of spectrum. Cognitive Radio (CR) is defined as the technology which handles the …

The Cognitive Radio (CR) continuously monitors the spectrum to detect the presence or
absence of the primary user. Cyclostationary is one the efficient spectrum sensing method …

Spectrum Sensing is the fundamental and essential operation in Cognitive Radio (CR) to
find the unused frequency bands. To detect the unused spectrum, different types of detectors …

In this paper, we have studied an adaptive decode-and-forward (ADF) relay based
cooperative spectrum sensing scheme in cognitive radio (CR) network in presence of …

We consider a cooperative spectrum sensing problem in which a relay user (RU) assists a
secondary user (SU) in order to detect the presence of a primary user (PU). We propose …
