Cognitive Radio offers a solution by utilizing the spectrum holes that represent the potential opportunities for non-interfering use of spectrum which requires three main tasks-spectrum sensing, spectrum analysis and spectrum allocation. Spectrum sensing involves obtaining the spectrum usage characteristics across multiple dimensions such as time, space, frequency and code and determining what type of signals are occupying the spectrum The development of a reliable and accurate spectrum sensing is very essential to propound quick and accurate detection of white spaces for better throughput of secondary user network under the constraint of the specified primary system protection.
