Addition of Fuzzy Logic-based Decision Making in Energy-based Spectrum Sensing Technique to Improve Detection Probability
Abstract: Everyday new applications have been created with the requirement of spectrum. Unavailability of spectrum band is not a right circumstance for the growing market. But due to the insufficient amount of band availability, CR (cognitive radio) methodology has been proposed. As per CR methodology, those applications which came under unlicensed band are suggested to use spectrum band of licensed user but after checking whether that band must be free and …

Machine Learning Bouc-Wen Model for Nano- positioning System
Abstract: Most of the application in present world has taken ‘Nano’ as a part of their near future implementation. In Nano-Positioning System (NPS) the mechanical dynamics are handled at Nano scale. Designing a precisioned NPS is a greater challenge. To have a better hysteresis and better behaviour (Static/Dynamic) the Bouc-Wen model is modified by linearizing. In this work SISO (Sıngle-input Sıngle-Output) and MIMO (Multiple-Input Multiple-Output) models of NPS are designed. In …
