Study and Analysis of Spectrum Sensing Techniques and Implementation of Matched Filters in Cognitive Radio Systems
Spectrum sensing is an essential enabling functionality for cognitive radio networks to detect spectrum holes and opportunistically use the under-utilized frequency bands without causing harmful interference to legacy networks. This paper introduces a novel wideband spectrum sensing technique, called multiband joint detection, which jointly detects the signal energy levels over multiple frequen...
متن کاملImplementation 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...
متن کاملExperimental 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...
متن کاملAnalysis of Protocols for Spectrum Sensing in Cognitive Radio Networks
Cognitive Radio allows opportunistic spectrum access (OSA) of licensed frequency bands by unlicensed users so as to reduce spectrum scarcity led by the increasing market demands. Spectrum sensing is an essential mechanism for a cognitive radio system. Therefore attention should be given towards the security aspects of spectrum sensing in cognitive radio. This paper analyses the two protocols me...
متن کاملEntropic Analysis of Spectrum Sensing for Cognitive Radio
The rapid proliferation of wireless communications has brought many exciting new technologies that require ever more spectrum. A recent FCC study noted that spectrum utilization exhibits large geospatial and temporal variances. As the number of wireless devices requiring spectrum access will undoubtedly increase, much effort has gone into exploiting the results from this study. The current stra...
