Modern wireless mobile communication system concentrates on effective utilization of frequency band and efficient modulation technique for side lobe elimination. Frequency bands are effectively utilized by using Cognitive radio networks. Cognitive radio network (CRN) is one of the intelligent technologies to solve spectrum scarcity. Universal Filtered Multi-Carrier (UFMC) is the potential multi-carrier...
The Cognitive Radio is a smart wireless communication system that provides awareness about the radio frequency spectrum of its surroundings and rapidly reconfigures its operating parameters dynamically. It is a methodology to use the currently available spectrum momentarily without interfere the licensed user. This paper focuses on the challenges associated with network spectrum sensing, by employing...
