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

Performance of wideband spectrum sensing under fading channel
2015 Seventh International Workshop on Signal Design and its Applications in Communications (IWSDA), 2015In this paper, we study the performance of the wideband spectrum sensing for cognitive radio network under different fading channels. We compare the performance of wideband spectrum sensing where each channel in the band undergoes fading with that of additive white Gaussian noise channel.

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 ...

Compressive Wideband Frequency Spectrum Sensing Based on MUSIC
2019 International Conference on Artificial Intelligence in Information and Communication (ICAIIC), 2019Locating multiple active subbands in wide frequency range is an important application of spectrum sensing in cognitive radio systems. While a high Nyquist sampling rate required by an analog-to-digital converter (ADC) devices becomes a common burden in this field, inaccurate frequency band estimation also becomes a severe problem leading to ...
