ED-SS based Cognitive Radio (CR) over Rayleigh Fading Channel and the Performance of Optimized Cooperative Spectrum Sensing Technique for Modern Wireless Communications
Abstract: Cognitive Radio (CR) has indeed been shown to be a superior way to address the issue of spectrum scarcity in which every wireless system occupies the limited bandwidth spectrum (LBS) allotting to the licensed users. Spectrum holes, which are approximated using spectrum sensing, occur when this LBS is empty in a certain location at a specific moment (SS). The SS is the main objective of CR and various SS techniques …

Study of Cooperative Spectrum Sensing Techniques in Cognitive Radio Networks
Abstract: Cognitive radio is key enabling technology that enables next generation communication networks, also known as dynamic spectrum access network, to utilize the spectrum more efficiently in an opportunistic fashion without interfering with the licensed user. Its roots came from the discovery by regulatory bodies in various countries, which found that most of the radio frequency spectrum was inefficiently utilized. This was the reason for allowing unlicensed users to utilize licensed …

Heterogeneous Spectrum Sensing in Cognitive Radio Network using Enhanced Energy Detection and Matched Filter
Abstract: AbstractOne of the most predominant aspect in cognitive radio networks is spectrum sensing which allows a secondary user (unlicensed user) to detect the presence or absence of a primary user (licensed user). A number of sensing techniques have been proposed in the past. In order to achieve a high spectrum efficiency, the compatibility of the common spectrum detection techniques primarily used such as energy detection and matched filter are employed …
