This paper presents cooperative spectrum sensing techniques for cognitive radio (CR)
systems. The spectrum sensing detects the presence of a primary user (service) on an …

Cognitive radio introduces spectrum sharing between primary licensed user and many
secondary users, while successful spectrum sharing depends on the correct detection of …

This paper proposes a novel scheme for cooperative spectrum sensing on distributed
cognitive radio networks. A fuzzy logic rule-based inference system is proposed to estimate …

Spectrum sensing is a key functionality of Cognitive Radio to detect the availability of
Primary User (PU) in a licensed band. However, the local sensing performance of Cognitive …

In cognitive radio networks (CRN), spectrum sensing requires each secondary user to
efficiently and effectively detect the presence of primary users. In this paper, we study …

Cooperative spectrum sensing for cognitive radio networks is recently being studied to
simultaneously minimize uncertainty in primary user detection and solve hidden terminal …

In cognitive radio (CR) systems, cognitive users can use the frequency bands when the
primary users are not present. Hence, reliable detection of available spectrum is foundation …

Spectrum sensing is one of the key technologies to realize spectrum reuse and increase the
spectrum efficiency in cognitive radio networks (CRNs). In this paper, we study energy …

In this paper, we propose a cooperative spectrum sensing scheme to maximize the detection
probability in cognitive radio systems. We first analytically derive a closed-form expression …

Spectrum sensing is a key technology in cognitive radio (CR). It provides the CR system with
available vacant channels list by sensing the spectrum environment over a wide frequency …
