Two Stage Spectrum Sensing for Cognitive Radio using Cyclostationarity detection and Energy Detection
Dynamic spectrum access (DSA) is a promising approach for the more effective use of existing spectrum. Of fundamental importance to DSA is the need for fast and reliable spectrum sensing over a wide bandwidth. Cognitive radio is an intelligent wireless communication technology in order to increase the spectrum efficiency. Increasing efficiency of the spectrum usage is an urgent need as an intri...
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 کاملImproved energy detection spectrum sensing for cognitive radio
Energy detection constitutes a preferred approach for spectrum sensing in cognitive radio due to its simplicity and applicability (it works irrespective of the signal format to be detected) as well as its low computational and implementation costs. The main drawback, however, is its well-known detection performance limitations. Various alternative detection methods have been shown to outperform...
متن کاملEnergy Detection Technique for Spectrum Sensing in Cognitive Radio
With unprecedented growth of the subscribers in modern cellular and wireless data communications, there is an acute scarcity of additional bandwidth to meet the ever growing demand. To ease the constraint of additional bandwidth, utilization of the existing system has been a topic of recent interest. Cognitive Radio is a new technique in which the spectral holes in unutilized spectrum are deter...
متن کاملEnergy Detection Based Spectrum Sensing Technique for Software Defined Radio
A lot of hardware components are used to make a conventional radio communication system, the complexity of these hardware can be reduced with help of Software Defined Radio (SDR) which is a form of wireless communication. Software Defined Radio implemented system allows us to make alteration in it or operate it with help of a software, thus making the system flexible and reconfigurable. The sys...
