Considering the continuance feature of the spectrum idle state observed from our spectrum
measurements, in this paper, we propose a novel SK ipping b A sed spec T rum s E nsing …

Cognitive radio (CR) for dynamic spectrum sensing and access has been a hot research
topic in recent years. To avoid collision with the primary users, secondary users need to …

In a periodic spectrum sensing framework where each frame consists of a sensing block and
a data transmitting block, increasing sensing duration decreases the probabilities of both …

Spectrum sensing is a key functionality in cognitive radio to avoid unacceptable interference
to primary users. When channel traffic becomes heavy, channel state switches within a …

In cognitive radio systems based on periodic sensing and transmission, a secondary user
(SU) senses the activity of a primary user (PU) in the sensing phase and then makes use of …

This paper focuses on the spectrum sensing mechanisms, which could improve network
throughput through the sensing strategy optimization and cooperative spectrum sensing …

Spectrum sensing is a critical issue in a cognitive radio (CR). In this paper, we propose a
novel spectrum-sensing algorithm that exploits the time diversity of sensing results …

In this paper, we consider a cognitive radio (CR) system with a single secondary user (SU)
and multiple licensed channels. The SU requests a fixed number of licensed channels and …

Cognitive radio sensor networks are one of the kinds of application where cognitive
techniques can be adopted and have many potential applications, challenges and future …

Cognitive radio technology, which helps to alleviate spectrum scarcity problem, plays an
important role in future wireless communication systems. Spectrum sensing is the key …
