Implementation of Spectrum Sensing Techniques for Cognitive Radio Systems

This work presents a method for real-time detection of secondary users at the cognitive wireless technologies base stations. Cognitive radios may hide themselves in between the primary users to avoid being charged for spectrum usage. To deal with such scenarios, a cyclostationary Fast Fourier Transform accumulation method (FAM) has been used to develop a new strategy for recognising channel use...

Kurtosis based spectrum sensing in cognitive radio

In this paper, we consider spectrum sensing in cognitive radio networks based on higher order statistics. The kurtosis, a fourth order statistic, which is a measure of deviation from Gaussianity, is used as a detection statistic. An optimum threshold is set up based on the Neyman-Pearson criterion and analytical expression for upper bound on probability of miss is derived for a single pair of p...

Experimental Implementation of Spectrum Sensing Using Cognitive Radio

Cognitive radio (CR) is designed to detect available frequency bands/channels. Spectrum sensing plays a critical role in CR with energy detection being the most common method. In our paper, we implement energy detection using GNU Radio and USRP boards as a test-bed. Specifically, energy detection is performed by using blocks in GNU Radio Companion (GRC) to calculate the energy of a present sign...

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...

Spectrum 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...
