1Spectrum Sensing Based on Deep Learning Classification for Cognitive Radios显示文摘Spectrum sensing is a key technology for cognitive radios.We present spectrum sensing as a classification problem and propose a sensing method based on deep learning classification.We normalize the received signal power to overcome the effects of noise power uncertainty.We train the model with as many types of signals as possible as well as noise data to enable the trained network model to adapt to untrained new signals.We also use transfer learning strategies to improve the performance for real-world signals.Extensive experiments are conducted to evaluate the performance of this method.The simulation results show that the proposed method performs better than two traditional spectrum sensing methods,i.e.,maximum-minimum eigenvalue ratio-based method and frequency domain entropy-based method.In addition,the experimental results of the new untrained signal types show that our method can adapt to the detection of these new signals.Furthermore,the real-world signal detection experiment results show that the detection performance can be further improved by transfer learning.Finally,experiments under colored noise show that our proposed method has superior detection performance under colored noise,while the traditional methods have a significant performance degradation,which further validate the superiority of our method.Shilian Zheng Shichuan Chen Peihan Qi Huaji Zhou Xiaoniu Yang 2020China Communications2020,17,2:16

3Generative Adversarial Network-Based Electromagnetic Signal Classification: A Semi- Supervised Learning Framework显示文摘Generative adversarial network(GAN)has achieved great success in many fields such as computer vision,speech processing,and natural language processing,because of its powerful capabilities for generating realistic samples.In this paper,we introduce GAN into the field of electromagnetic signal classification(ESC).ESC plays an important role in both military and civilian domains.However,in many specific scenarios,we can’t obtain enough labeled data,which cause failure of deep learning methods because they are easy to fall into over-fitting.Fortunately,semi-supervised learning(SSL)can leverage the large amount of unlabeled data to enhance the classification performance of classifiers,especially in scenarios with limited amount of labeled data.We present an SSL framework by incorporating GAN,which can directly process the raw in-phase and quadrature(IQ)signal data.According to the characteristics of the electromagnetic signal,we propose a weighted loss function,leading to an effective classifier to realize the end-to-end classification of the electromagnetic signal.We validate the proposed method on both public RML2016.04c dataset and real-world Aircraft Communications Addressing and Reporting System(ACARS)signal dataset.Extensive experimental results show that the proposed framework obtains a significant increase in classification accuracy compared with the state-of-the-art studies.Huaji Zhou Licheng Jiao Shilian Zheng Lifeng Yang Weiguo Shen Xiaoniu Yang 2020China Communications2020,17,10:8

5Ambient Backscatter Communications over NOMA Downlink Channels显示文摘In this paper,we investigate the performance of commensal ambient backscatter communications(AmBC)that ride on a non-ortho go nal multiple access(NOMA)downlink transmission,in which a backscatter device(BD)splits part of its received signals from the base station(BS)for energy harvesting,and backscatters the remaining received signals to transmit information to a cellular user.Specifically,under the power consumption constraint at BD and the peak transmit power constraint at BS,we derive the optimal reflection coefficient at BD,the optimal total transmit power at BS,and the optimal power allocation at BS for each transmission block to maximize the ergodic capacity of the ambient backscatter transmission on the premise of preserving the outage performance of the NOMA downlink transmission.Furthermore,we consider a scenario where the BS is restricted by a maximum allowed average transmit power and the reflection coefficient at BD is fixed due to BD’s low-complexity nature.An algorithm is developed to determine the optimal total transmit power and power allocation at BS for this scenario.Also,a low-complexity algorithm is proposed for this scenario to reduce the computational complexity and the signaling overheads.Finally,the performance of the derived solutions are studied and compared via numerical simulations.Weiyu Chen Haiyang Ding Shilian Wang Daniel Benevides daCosta Fengkui Gong Pedro Henrique Juliano Nardelli 2020China Communications2020,17,6:4
6MIMO-DCSK communication scheme and its performance analysis over multipath fading channels显示文摘The differential chaotic shift keying(DCSK) communication in multiple input multiple output(MIMO) multipath fading channels is considered. A simple MIMO-DCSK communication scheme based on orthogonal multi-codes(OMCs) and equal gain combination(EGC) is proposed, in which OMCs are used to spread the same information bit at each transmitting antenna and the information bit is detected by EGC at receiving antenna. The OMCs are constructed from one chaotic sequence by means of othogonal space-time block coding(OSTBC). The output signal-to-noise ratio(SNR) after EGC is given based on central limit theory(CLT),and it can effectively exploit the spatial diversity of the underlying MIMO system. Simulation results show that the full spatial diversity gain is achieved without channel estimation in the MIMO-DCSK communication scheme and it performs better than MC-EGC for a large number of transmitting antennas.Shilian Wang Shujun Lu Eryang Zhang 2013Journal of Systems Engineering and Electronics2013,24,5:4
7Primary User Adversarial Attacks on Deep Learning-Based Spectrum Sensing and the Defense Method显示文摘The spectrum sensing model based on deep learning has achieved satisfying detection per-formence,but its robustness has not been verified.In this paper,we propose primary user adversarial attack(PUAA)to verify the robustness of the deep learning based spectrum sensing model.PUAA adds a care-fully manufactured perturbation to the benign primary user signal,which greatly reduces the probability of detection of the spectrum sensing model.We design three PUAA methods in black box scenario.In or-der to defend against PUAA,we propose a defense method based on autoencoder named DeepFilter.We apply the long short-term memory network and the convolutional neural network together to DeepFilter,so that it can extract the temporal and local features of the input signal at the same time to achieve effective defense.Extensive experiments are conducted to eval-uate the attack effect of the designed PUAA method and the defense effect of DeepFilter.Results show that the three PUAA methods designed can greatly reduce the probability of detection of the deep learning-based spectrum sensing model.In addition,the experimen-tal results of the defense effect of DeepFilter show that DeepFilter can effectively defend against PUAA with-out affecting the detection performance of the model.Shilian Zheng Linhui Ye Xuanye Wang Jinyin Chen Huaji Zhou Caiyi Lou Zhijin Zhao Xiaoniu Yang 2021China Communications2021,18,12:3

Significant progresses have been made on the synthesis of micro/nanostructures with efficient SERS response. In this review, we mainly focus on the various PS template-based fabrication techniques in realizing micro/nanostructured arrays and the SERS applications.XiaoLei Zhang ZhiGao Dai XinGang Zhang ShiLian Dong Wei Wu ShiKuan Yang XiangHeng Xiao ChangZhong Jiang 2016Science China(Physics,Mechanics & Astronomy)2016,59,12:2
10AUREA maintains the balance between chlorophyll synthesis and adventitious root formation in tomato显示文摘Flooding tolerance is an important trait for tomato breeding.In this study,we obtained a recessive mutant exhibiting highly enhanced submergence resistance.Phenotypical analyses showed that this resistant to flooding(rf)mutant displays slightly chlorotic leaves and spontaneous initiation of adventitious roots(ARs)on stems.The mutation was mapped to the phytochromobilin synthase gene AUREA(AU),in which a single amino acid substitution from asparagine to tyrosine occurred.In addition to the classic function of AU in phytochrome and chlorophyll biogenesis in leaves,we uncovered its novel role in mediating AR formation on stems.We further observed temporal coincidence of the two phenotypes in the rf mutant:chlorosis and spontaneous AR formation and revealed that AU functions by maintaining heme homeostasis.Interestingly,our grafting results suggest that heme might play roles in AR initiation via long-distance transport from leaves to stems.Our results present genetic evidence for the involvement of the AU–heme oxygenase-1–heme pathway in AR initiation in tomato.As fruit production and yield in the rf mutant are minimally impacted,the mutation identified in this study may provide a target for biotechnological renovation of tomato germplasm in future breeding.Junqing Wu Jie Cheng Chunmiao Xu Shilian Qi Wenru Sun Shuang Wu 2020Horticulture Research2020,7,1:2

13PI3K/Akt signaling pathway involved in regulation of T lymphocyte activation and apoptosis mediated by CD3ε显示文摘To study the expression and kinase activity of phosphatidylinositol 3’ -kinase (PI3K) and protein kinase B (PKB or Akt) during activation and apoptosis of human Jur-kat T lymphocytes (TJK) with stable expression of CD8ε chimera fused human CD8α extracellular and transmembrane domains to intracellular domain of mouse CD3ε, Western blot, kinase activities detection and immunoprecipitation were carried out It was shown that Jurkat cells with expression of wild type chimera CDSε died by apoptosis after continuous stimulation of anti-CD8 monoclonal antibody. The expressions of PI3K and Akt, and the kinase activity of Akt remarkably increased during the process. However, this phenomenon did not occur in the Jurkat cells (T1JK) with expression of the mutant of CD8ε chimera (Y170F), suggesting that PI3K/Akt signaling pathway is involved in activation and apoptosis of T lymphocyte mediated by CD3ε.ZHANG Jing, LIU Yanxin, LIU Shilian & ZHENG DexianNational Laboratory of Medical Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences, Beijing 100005, China 2001Chinese Science Bulletin2001,46,7:1

15Few-shot electromagnetic signal classification:A data union augmentation method显示文摘Deep learning has been fully verified and accepted in the field of electromagnetic signal classification. However, in many specific scenarios, such as radio resource management for aircraft communications, labeled data are difficult to obtain, which makes the best deep learning methods at present seem almost powerless, because these methods need a large amount of labeled data for training. When the training dataset is small, it is highly possible to fall into overfitting, which causes performance degradation of the deep neural network. For few-shot electromagnetic signal classification, data augmentation is one of the most intuitive countermeasures. In this work, a generative adversarial network based on the data augmentation method is proposed to achieve better classification performance for electromagnetic signals. Based on the similarity principle, a screening mechanism is established to obtain high-quality generated signals. Then, a data union augmentation algorithm is designed by introducing spatiotemporally flipped shapes of the signal. To verify the effectiveness of the proposed data augmentation algorithm, experiments are conducted on the RADIOML 2016.04C dataset and real-world ACARS dataset. The experimental results show that the proposed method significantly improves the performance of few-shot electromagnetic signal classification.Huaji ZHOU Jing BAI Yiran WANG Licheng JIAO Shilian ZHENG Weiguo SHEN Jie XU Xiaoniu YANG 2022Chinese Journal of Aeronautics2022,35,9:1
