detection is essential. This research paper proposed an advance spectrum sensing …

With the increasing number of wireless users every day, cognitive radio serves as an
approach to solve the spectrum crunch problem. Spectrum sensing serves as the heart of …

In this correspondence, the authors propose a nonuniform quantized data fusion (N-QDF)
rule alleviating control channel overhead for energy detection based cooperative spectrum …

Accurate spectrum sensing is highly recommended in interweave cognitive radio systems. In
this paper, cooperative spectrum sensing based on censored energy detection is …

Spectrum sensing is the key component of cognitive radio technology. However, detection is
compromised when a user experiences shadowing or fading effects. Thus, cooperative …

Cognitive radio has become an effective technology to solve the underutilisation problem of
the spectrum. In recent times, spectrum sensing has been intensively studied as a key …

Accurate spectrum sensing plays a decisive role in determining the performance of any
cognitive radio network (CRN). Spectrum sensing enables the unlicensed secondary users …

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 …

Cognitive Radio (CR) can be viewed as a novel approach to improve the overall Spectrum
utilisation. In a CR, the most challenging operation is to detect the presence of any unutilized …

Spectrum sensing in cognitive radio is a crucial task for detecting spectrum opportunities.
Due to the intense demand for the frequency spectrum, average spectrum occupancy has …
