Matched-Filter-based Spectrum Sensing for Secure Cognitive Radio Network Communications
The increasing demand for wireless communication introduces efficient spectrum utilization challenge. To address this challenge, Cognitive Radio (CR) has emerged as the key technology, which enables opportunistic access to the spectrum. However, security is a very important issue but not well addressed in CR networks. In this paper, we focus on security problems arising from Primary User Emulat...
متن کاملPerformance evaluation of Matched Filter Detection Based on Non-Cooperative Spectrum Sensing in Cognitive Radio Network
The recent and rapid evolution of wireless technologies has led to a high demand in terms of resources. To solve this prob-lem the idea of cognitive radio has been introduced to facilitate a good spectrum management and efficient use of the spectrum. In this article, a method for the detection of the spectrum with the purpose of detecting the presence of bands of unoccupied frequencies is propo...
متن کاملMatched Filter Based Spectrum Sensing for Cognitive Radio at Low Signal to Noise Ratio
Custom usage of a Cognitive Radio is administrated by the essential utilization aspect of the radio spectrum the natural resource. Cognitive radio trying to resourcefully share the radio spectrum along with potential primary users in the spectrum that must be identified in order to evade causing harmful interference with other users on the spectrum. The vibrant usage of spectrum belongs to the ...
متن کاملMatched Filter Based Spectrum Sensing on Cognitive Radio for OFDM WLANs
Abstract For the unlicensed users to use the licensed spectrum, unused frequency bands called white spaces need to be detected. Cognitive radio does this task by dynamic spectrum access. This requires intelligent spectrum sensing techniques. In this paper such unused spectrum for OFDM WLAN (IEEE 802.11a) is predicted by exploring the signals presence in minimum time using matched filter based d...
