Adaptive Double-threshold Joint Spectrum Sensing Based on Energy detection
Energy sense of adaptive double threshold joint spectrum perception algorithm using multiple cognitive, and after double threshold for comprehensive judgment, and threshold value with the discretion of the signal to noise ratio (SNR) adaptive adjustment, will eventually each SU decision data fusion center for spectrum using the information, make perception performance effectively improve. In th...
متن کاملDouble Threshold Cooperative Spectrum Sensing Algorithm Based on Energy and Eigenvalue of Signal
In this paper, we propose a double threshold detection algorithm for spectrum sensing in cognitive radio. Firstly, we set two decision thresholds for each secondary user based on the energy detection method. And then each secondary user reports its local decision or observational signal to the fusion center. If there is more than one secondary user report that the transmitted signal is present,...
متن کاملDouble-Threshold Cooperative Spectrum Sensing Algorithm Based on Sevcik Fractal Dimension
Spectrum sensing is of great importance in the cognitive radio (CR) networks. Compared with individual spectrum sensing, cooperative spectrum sensing (CSS) has been shown to greatly improve the accuracy of the detection. However, the existing CSS algorithms are sensitive to noise uncertainty and are inaccurate in low signal-to-noise ratio (SNR) detection. To address this, we propose a double-th...
متن کاملImproved Double Threshold Energy Detection for Cooperative Spectrum Sensing in Cognitive Radio
In this paper, we focus on cooperative spectrum sensing (CSS) for double threshold improved energy detector. In this method, the improved energy detector compares positive power operation p of the amplitude of received signals at each secondary user (SU) with two thresholds to make binary decision about presence or absence of primary user (PU). The energies lying between upper and lower thresho...
متن کاملAdaptive Double Threshold based Spectrum Sensing for Cognitive Radio Networks
Rapid growth of wireless communication and limited spectrum availability to support the applications and services, has led to the development of cognitive radio as promising solution to address the problem of spectrum scarcity. Spectrum sensing is one of the fundamental functions towards the implementation of the cognitive radio concept in wireless communication. In this paper, we present an ad...
