In an interweave cognitive radio system, cooperative spectrum sensing has been
recognised as a key technology to enable secondary users to opportunistically access …

In cognitive radio (CR), the detection performance of traditional spectrum sensing may be
decreased due to the multipath fading and shadowing effect. However, unmanned aerial …

Cooperative spectrum sensing (CSS) involves multiple secondary users (SUs) reporting
primary user (PU) channel sensing states to the fusion center (FC). However, the high …

Typically, each cooperative spectrum sensing process requires two phases: the primary
user's signal detection phase, in which all cognitive users attempt to detect the presence of …

In cognitive radio (CR) networks, cooperative spectrum sensing is utilized to improve the
sensing performance to avoid potential interference to primary users (PUs) and increase …

In cooperative spectrum sensing (CSS), a multibit combination rule shows better sensing
performance than one-bit hard combination rules at the sacrifice of the reporting overhead …

Cooperative spectrum sensing (CSS) is a key enabling technology of cognitive radio
networks with multiple secondary users (SUs). In conventional CSS systems, when the …

In this paper, we study the distributed cooperative spectrum sensing in heterogeneous
cognitive radio networks, where each secondary user (SU) adopts a different spectrum …

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

The cognitive radio (CR) technology is being considered as a novel approach for improving
the spectrum utilization by detecting and using the vacant spectrum bands of licensed users …
