Distributed Compressive Sensing Augmented Wideband Spectrum Sharing for Cognitive IoT
Xingjian Zhang,Yuan Ma,Haoran Qi,Yue Gao,Zhixun Xie,Zhiqin Xie,Zhang Minxiu,Wang Xiaodong,Wei Guangliang,Li Zheng +9 more
TL;DR: A blind joint sub-Nyquist sensing scheme is proposed by utilizing the surround IoT devices to jointly sample the spectrum based on the multicoset sampling theory and it is shown that the adaptive number of coset samplers could be adopted without causing the degradation of the detection performance and the number ofcoset sampler could be further reduced with the assists from geo-location database even when the obtained information is partially correct.
Journal ArticleDOI
AI-Based Abnormality Detection at the PHY-Layer of Cognitive Radio by Learning Generative Models
Andrea Toma,Ali Krayani,Muhammad Farrukh,Haoran Qi,Lucio Marcenaro,Yue Gao,Carlo S. Regazzoni +6 more
TL;DR: This work proposes and implements Artificial Intelligence (AI)-based Abnormality Detection techniques at the physical (PHY)-layer in CR enabled by learning Generative Models and shows that both of the proposed methods are capable of detecting abnormal signals in the spectrum and pave the road towards Self-Aware radio.
Journal ArticleDOI
Learning to Predict the Mobility of Users in Mobile mmWave Networks
TL;DR: A deep neural network is learned and then used to predict a user's moving direction with up to 80 percent prediction accuracy in mmWave communication without the support of traditional channel estimation.
Journal ArticleDOI
Channel Energy Statistics Learning in Compressive Spectrum Sensing
Haoran Qi,Xingjian Zhang,Yue Gao +2 more
TL;DR: A statistical model of channel energy for CSS is postulated and a practical threshold adaption scheme is proposed aiming to maintain constant false alarm rates in channel energy detection to investigate the channel energy statistics of recovered spectrum.
Journal ArticleDOI
Low-Complexity Subspace-Aided Compressive Spectrum Sensing Over Wideband Whitespace
Haoran Qi,Xingjian Zhang,Yue Gao +2 more
TL;DR: A novel spectrum sparsity estimation scheme directly from sub-Nyquist measurements is proposed, with which the computational effort of greedy pursuit algorithms can be saved and recovery performance improved and the detection performance and complexity of the proposed CSS scheme show striking superiority against multiple benchmarking schemes.
