| 1 | Tiny YOLO Optimization Oriented Bus Passenger Object Detection显示文摘The real-time collection of bus passenger object detection is an essential part of developing a smart bus system.The difficulty of object detection mainly lies in the objective factors,such as:clothing,hair style and accessories,light,etc.Traditional object detection met hods with the arti ficial feature ext rac tion suffers from insufficien t st reng th in expression,generalization,and recogni tion rate.The objec t detection met hod based on deep learning mainly uses the convol utio nal neural net work in deep learning to learn features from a large set of data.The learned features can describe the rich infbrmation inherent in the data,and improve the expression ability of the features as well as the recognition accuracy.Due to too many parameters of the Convolutional neural network(CNN)model,the amount of calculation is too large to be opera ted on the vehicle terminal.To reduce calculation burden and improve the operation speed,we employs the depthwise separable convolution method to optimize the convolutional layer of tiny YOLO net work model.It decomposes a complete convolution operation into depthwise convolution and pointwise convolution,thus reducing the parameter amount of the CNN and improving the operation speed.The experiment results reveal that the speed of bus passenger object detection detected by our improved model is 4 times faster than the previous one but with the nearly same detection accuracy. | ZHANG Shuo WU Yanxia MEN Chaoguang LI Xiaosong | 2020 | Chinese Journal of Electronics2020，29，1： | 15 |
| 2 | Blind adaptive receiver based on RLS-CMA for TH-UWB system显示文摘A novel receiver is proposed in this paper that uses the blind adaptive multi-user detection(MUD) technique to deal with the presence of multiple-access interference(MAI) and inter-symbol interference(ISI) in terms of high speed time-hopping ultra-wideband(TH-UWB) system.The receiver firstly adopts constrained recursive least squares constant modulus algorithm(RLS-CMA) to conduct adaptive decorrelation for eliminating MAI and ISI,and then uses projection approximation subspace tracking with deflation(PASTd) algorithm to launch channel estimation,do maximal ratio combining(MRC) and improve signal to interference plus noise ratio(SINR).The simulation results show that the proposed receiver can go to convergence rapidly under all four IEEE's UWB channel models,the bit error ratio(BER) performance is better than that of the traditional receiver and rake receiver. | KANG Xiao-fei YANG Jia-wei MEN Shuo | 2011 | The Journal of China Universities of Posts and Telecommunications2011，18，6： | 3 |

| 4 | Cooperative blind spectrum sensing using autocorrelation matrix显示文摘To improve the spectrum sensing performance in cognitive radios,a scheme of cooperative blind spectrum sensing based on autocorrelation matrix is proposed.The test statistic is extracted from the autocorrelation matrix of the received signal samples and a bi-threshold hybrid decision scheme is designed for local spectrum sensing.The cognitive radio base station makes a credibility fusion based on the local soft decisions and then takes global fusion combining with the local hard decisions.The proposed method is blind in the sense since it requires no apriori knowledge of the signal and the noise power.Theoretical analysis and computer simulation results show that the proposed method can enhance the spectrum sensing capability. | JIAO Chuan-hai WANG Ke-ren MEN Shuo | 2011 | The Journal of China Universities of Posts and Telecommunications2011，18，3： | 1 |
| 5 | Design and analysis of quantized controllable doped left-handed materials显示文摘Two kinds of controllable doped left-handed materials (DLHMs) were designed by inserting inductors and capacitors into the traditional left-handed material (LHM) as heterogeneous elements respectively,which are DLHM with inductors (LDLHM) and DLHM with capacitors (CDLHM).The characteristics of transmission spectrum were studied by using finite-difference time-domain method (FDTD).Compared with the traditional LHM,the resonance strength of the LDLHM is weakened and the pass-band is narrowed,but with the increase of the value of the inserted inductors,the bandwidth is expanded.As capacitors inserted into the LHM,the pass-band of the CDLHM is expanded,but the pass-band is shifted to low frequency and the bandwidth is narrowed with the increase of the value of the capacitors,meanwhile,a new generated pass-band is also shifted to low frequency.Therefore,a quantized controllable doped left-handed material can be achieved. | LIU Wen ZHANG Hong-xin WANG Hong LU Ying-hua CHEN Nan MEN Shuo | 2011 | The Journal of China Universities of Posts and Telecommunications2011，18，3： | 1 |
| 6 | Observatory science with eXTP显示文摘In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s. | Jean J.M.in 't Zand Enrico Bozzo JinLu Qu Xiang-Dong Li Lorenzo Amati Yang Chen Immacolata Donnarumma Victor Doroshenko Stephen A.Drake Margarita Hernanz Peter A.Jenke Thomas J.Maccarone Simin Mahmoodifar Domitilla de Martino Alessandra De Rosa Elena M.Rossi Antonia Rowlinson Gloria Sala Giulia Stratta Thomas M.Tauris Joern Wilms XueFeng Wu Ping Zhou Iván Agudo Diego Altamirano Jean-Luc Atteia Nils A.andersson M.Cristina Baglio David R.Ballantyne Altan Baykal Ehud Behar Tomaso Belloni Sudip Bhattacharyya Stefano Bianchi Anna Bilous Pere Blay Joao Braga Sφren Brandt Edward F.Brown Niccolo Bucciantini Luciano Burderi Edward M.Cackett Riccardo Campana Sergio Campana Piergiorgio Casella Yuri Cavecchi Frank Chambers Liang Chen Yu-Peng Chen Jér?me Chenevez Maria Chernyakova ChiChuan Jin Riccardo Ciolfi Elisa Costantini Andrew Cumming Antonino D'Aì Zi-Gao Dai Filippo D'Ammando Massimiliano De Pasquale Nathalie Degenaar Melania Del Santo Valerio D'Elia Tiziana Di Salvo Gerry Doyle Maurizio Falanga XiLong Fan Robert D.Ferdman Marco Feroci Federico Fraschetti Duncan K.Galloway Angelo F.Gambino Poshak Gandhi MingYu Ge Bruce Gendre Ramandeep Gill Diego G?tz Christian Gouiffès Paola Grandi Jonathan Granot Manuel Güdel Alexander Heger Craig O.Heinke Jeroen Homan Rosario Iaria Kazushi Iwasawa Luca Izzo Long Ji Peter G.Jonker Jordi José Jelle S.Kaastra Emrah Kalemci Oleg Kargaltsev Nobuyuki Kawai Laurens Keek Stefanie Komossa Ingo Kreykenbohm Lucien Kuiper Devaky Kunneriath Gang Li En-Wei Liang Manuel Linares Francesco Longo FangJun Lu Alexander A.Lutovinov Denys Malyshev Julien Malzac Antonios Manousakis Ian McHardy Missagh Mehdipour YunPeng Men Mariano Méndez Roberto P.Mignani Romana Mikusincova M.Coleman Miller Giovanni Miniutti Christian Motch Joonas Nättilä Emanuele Nardini Torsten Neubert Paul T.O'Brien Mauro Orlandini Julian P.Osborne Luigi Pacciani Stéphane Paltani Maurizio Paolillo Iossif E.Papadakis Biswajit Paul Alberto Pellizzoni Uria Peretz Miguel A.Pérez Torres Emanuele Perinati Chanda Prescod-Weinstein Pablo Reig Alessandro Riggio Jerome Rodriguez Pablo Rodríguez-Gil Patrizia Romano Agata Rózańska Takanori Sakamoto Tuomo Salmi Ruben Salvaterra andrea Sanna andrea Santangelo Tuomas Savolainen Stéphane Schanne Hendrik Schatz LiJing Shao andy Shearer Steven N.Shore Ben W.Stappers Tod E.Strohmayer Valery F.Suleimanov Jirí Svoboda F.-K.Thielemann Francesco Tombesi Diego F.Torres Eleonora Torresi Sara Turriziani andrea Vacchi Stefano Vercellone Jacco Vink Jian-Min Wang JunFeng Wang Anna L.Watts ShanShan Weng Nevin N.Weinberg Peter J.Wheatley Rudy Wijnands Tyrone E.Woods Stan E.Woosley ShaoLin Xiong YuPeng Xu Zhen Yan George Younes WenFei Yu Feng Yuan Luca Zampieri Silvia Zane andrzej A.Zdziarski Shuang-Nan Zhang Shu Zhang Shuo Zhang Xiao Zhang Michael Zingale | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，2： | 0 |
