Spectrum Sensing in Cognitive Radio
In modern wireless communications the spectrum is allocated to fixed licensed users and on the other side the number of wireless devices are increasing rapidly, that has lead to spectrum crunch. As the spectrum is precious it has to be utilized efficiently. The solution to mitigate this problem is Spectrum Sharing. One of the innovative approach to recognize and access the spectrum holes presen...
متن کاملSpectrum Sensing in Cognitive Radio
With the fast readying of latest wireless devices , the last decade has witnessed a growing demand for spectrum. However, the exploit spectrum assignment policy becomes a bottleneck for additional economical spectrum utilization, below that an excellent portion of the authorised spectrum is severely under-utilized. The inefficient usage of the restricted spectrum resources urges the spectrum re...
متن کاملBlind Spectrum Sensing Techniques for Cognitive Radio System
As the mobile communication environments grow rapidly, much attention has been paid on the use of spectrum resources. Recently, a new technology called Cognitive Radio (CR) was developed for using the unused spectrum bands efficiently. In the CR system, one possible way to locate these unused spectrum bands is to use so-called spectrum sensing. This technique, however, should be computationally...
متن کاملSpectrum Sensing with Energy Detection Techniques for Cognitive Radio System
DOI: 10.5281/zenodo.57992 ABSTRACT A cognitive radio by virtue of its ability to sense and adapt to the dynamic spectrum scenario, can increase the spectral efficiency .In order to be non invasive, a cognitive radio must adhere to strict benchmark in the quality of spectrum sensing for primary users of a band.Thus, spectrum sensing has a major role to play in cognitive radio .Many algorithms ha...
متن کاملSelective Cooperative Spectrum Sensing for Cognitive Radio System
Spectrum sensing is the basis of cognitive radio technology. Cooperative spectrum sensing has been shown to increase the reliability of spectrum sensing. To reduce sensing overhead and total energy consumption, it is recommended that the users with good performance should be selected to increase the sensing reliability. However, which of the cognitive users have the best detection performance i...
