In this paper, the authors explore the concept for dynamic spectrum allocation and investigate different aspects of spectrum sensing in Cognitive Radio (CR) technology. CR systems are radios with the ability to exploit their environment to increase spectral efficiency and capacity. CR technology explores, an opportunistic and promising technology to utilize available communication spectrum in efficient and dynamic way. It proposes secondary users to optimally utilize reserved frequency bands of primary users that are not occupied all the time by primary users. This increases spectrum efficiency of available communication spectra.
