Spectrum sensing is a vital phase in Cognitive Radio (CR) to identify the unutilized spectrum
for improving the spectrum utilization. Cooperative sensing is being used for spectrum …

Spectrum sensing is a method which is used to find out whether the channel is idle or not in
Cognitive Radio Network (CRN). Traditional methods are not much reliable due to the …

In cognitive radio network spectrum sensing is a fundamental element to detect the
presence of primary user. In this paper cooperative spectrum sensing scheme is employed …

Among variant kinds of spectrum sensing strategies in cognitive radio (CR) broadly studied
before, cooperative sensing is the most popular one to detect the primary user accurately …

Detection is compromised when a cognitive radio (CR) user experiences deep fading effect.
To detect the primary user (PU) more accurately in fading channels, CR users need to …

Recently proposed cooperative spectrum sensing method suggests that Cognitive Radio
(CR) users can detect the primary users at low SNR with less time and higher accuracy …

Spectrum sensing is the most appropriate method performed by cognitive radio for the
efficient utilization of RF spectrum without any harmful interference to the primary users. In …

The main idea of Cooperative Spectrum Sensing (CSS) is to improve detection performance.
Each Secondary User (SU) shares sensing information to collect data of the unused bands …

Cognitive Radio is a novel technology that can potentially improve the utilization efficiency of
the radio spectrum by opportunistically using the unused frequency bands. Spectrum …

In cognitive radios, there exist two kinds of detection errors: missed-detection errors and
false-alarm errors. These errors severely degrade sensing performance. In this paper, we …
