Performance Evaluation of Spectrum Detection in Cognitive Radio Network
In mobility management, detection of spectrum hole plays very important role for doing spectrum handoff mechanism. Operation of the cognitive radio depends on the spectrum sensing which is the most important task in case of cognitive radio network. Detection of spectrum holes (underutilized sub-bands of the radio spectrum) estimates average power, throughput and utilized time for each spectrum ...
متن کاملPerformance Evaluation of Spectrum Sensing Techniques in Cognitive Radio Network
Cognitive radio (CR) is a promising technique that offers a solution to the spectrum scarcity problem by dynamically exploiting the underutilization of the spectrum among the bands. There are numerous procedures to detect spectrum using CRs like energy detection (ED), matched filter detection (MFD), cyclostationary feature detection (CFD), waveform based detection (WBD) and so on. In this paper...
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 کاملEnergy Detection Performance of Spectrum Sensing in Cognitive Radio
Spectrum sensing is a challenging task for cognitive radio. Energy detection is one of the popular spectrum sensing technique for cognitive radio. In this paper we analyze the performance of energy detection technique to detect primary user (PU). Simulation results show that the probability of detection increases significantly when signal to noise ratio increases. It is also observed that the d...
متن کاملPerformance Evaluation of MIMO Based Spectrum Sensing in Cognitive Radio
In this paper, one of the most important aspect of the Cognitive Radio i.e. Spectrum Sensing is considered. A new technique based on Multiple Input Multiple Output (MIMO) antennas is proposed for Spectrum Sensing in Cognitive Radio. This paper shows the results which prove that the use of MIMO antennas increases the “Probability of Detection” and decreases the “Probability of Missed Detection” ...
