Wideband spectrum sensing algorithm based on frequency correlation
2013 15th IEEE International Conference on Communication Technology, 2013Without the priori information of interference system, iterative detection algorithm can make a good performance. However, most of current iterative energy detection algorithms are confined to the hypothesis that the SNR within the entire detecting band is the same, which is obviously unrealistic in realistic application, especially when the frequency ...

An Edge Detection Approach to Wideband Temporal Spectrum Sensing
2016 IEEE Global Communications Conference (GLOBECOM), 2016In wideband spectrum sensing, an unlicensed user determines which portions of a given band have been left idle by the licensed users. A historical deficiency of wideband spectrum sensing, the inability to detect signals with low duty cycle, was addressed in a recent paper, where wideband temporal spectrum sensing was introduced. We propose an algorithm

Method and apparatus for wideband spectrum sensing
2018Examples of wideband spectrum sensing techniques for cognitive radio are provided. The techniques permit undersampling (e.g., sub-Nyquist sampling) the spectrum band, which permits use of more cost effective electronic components (e.g., lower frequency analog-to-digital converters (ADC)). The techniques permit determination of whether there are any (or

SDR Implementation of Spectrum Sensing for Wideband Cognitive Radio
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015This paper provides experimental results of the edge detection and spectrum sensing algorithms for wideband cognitive radio networks which are recently proposed in [1] using software defined radio (SDR) platform. The considered algorithms employ ratio based test statistics for detecting the edges of all sub-bands and generalized energy detection (GED ...
