Wireless communication is an emerging and evergreen field of research and will continue to be so in the future. Increased demands in spectrum and users eventually result in spectral congestion. Cognitive Radio systems provide an intelligent and an attractive solution to this problem. Spectrum Sensing is the main key for the functioning of Cognitive Radio and helps in efficient spectrum utilization...
With the advent of an era of wireless communication, the number of users is on the rise, the result of which is spectral congestion. Cognitive Radio systems provide an intelligent and an attractive solution to this technical crisis. Spectrum Sensing is indispensable for the functioning of Cognitive Radio and helps in efficient spectrum utilization. In this paper, a wavelet based approach to spectrum...
With congested wireless spectrum and increasing number of users, cognitive radio serve as a panacea for efficient spectrum utilization. This stands to substantiate the amount of research happening in this area. Spectrum sensing is indubitably a key functionality in cognitive radio, which helps determining the spectral holes and white spaces for the secondary users to communicate. In this paper, the...
