IET Communications pp. As more user applications emerge for wireless devices, the corresponding amount of traffic is rapidly expanding, with the corollary that ever-greater spectrum capacity is required. Service providers are experiencing deployment blockages due to insufficient bandwidth being available to accommodate such devices.
TVWS spectrum has materialised from the unused TV channels in the switchover from analogue to digital platforms.
Furthermore, by framing a novel margin strategy utilising a keep out contour, the hidden node issue is resolved and a viable secondary user sensing solution formulated. In this work, we will see how the cognitive technology works when has to access the spectrum.go here
A New Dynamic Spectrum Access Algorithm for TV White Space Cognitive Radio Networks
We will discuss and review some recent patents focusing on the following topics: how the system recognizes the best frequency, and how it changes the frequencies to log on the spectrum. At the end of the paper, we will discuss the importance of this new methodology along with future developments, keeping in view the pros and cons. Keywords: Cognitive radio, cognition cycle, dynamic spectrum access, primary user detection, spectrum management, spectrum sensing.
Abstract: Radio Communication is one of the research fields that is continuously improving and innovating. Volume 6 , Issue 3 , The analysis reveals that there exist three operating points that possibly maximise the system spectral efficiency: either both Ultra-wideband UWB is a useful radio technique for sharing frequency bands between radio systems.

Cognitive Radio as Enabling Technology for Dynamic Spectrum Access
We propose in this paper a detection algorithm based on a cost function that jointly tests the correlation induced by the cyclic prefix and the fact that this correlation is time-periodic. In the first part of Authors: Pierre Jallon.
Cognitive radios have the potential to vastly improve communication over wireless channels. We outline recent information theoretic results on the limits of primary and cognitive user communication in single a In the future, there will be a growing need for more flexible but efficient utilization of radio resources.
Increased flexibility in radio transmission, however, yields a higher likelihood of interference owin
