This paper presents an improved energy detector (ED) with weights to improve detection
performance in this situation that the primary user's status changes as arriving or leaving …

In this paper, we discuss a method to construct a radio environment map (REM) in an
environment with multiple primary users (PUs). The REM provides statistical information …

Cognitive radio (CR) is defined as a procedure that uses the range with and without
impedance. Elements of psychological radio systems incorporate spectrum sensing …

Passive multistatic radar is of great interest in both civilian and military applications due to its
numerous advantages. We focus on the target detection problem in passive multistatic radar …

Cognitive Radio (CR) is considered an intelligent technology. It improves the utilization of
the radio spectrum. The increasing number of new devices has resulted in growing …

Cognitive radio (CR) networks are an intelligent wireless communication technology that is
aware of its surrounding environment. The main process of the cognitive radio is spectrum …

Dynamic spectrum access (DSA) is a promising platform to solve the problem of spectrum
shortage for which the most challenging issue is spectrum allocation under uncertain …

For internet of things (IoT) implementation based on upcoming fifth generation (5G) mobile
networks, the spectrum sensing (SS) capabilities should be considered following the related …
