| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | A Fuzzy PID Algorithm for a Novel Miniature Spherical Robots with Three-dimensional Underwater Motion Control显示文摘We proposed and developed a small bionic amphibious spherical robot system for tasks such as coastal environment monitoring and offshore autonomous search and rescue.Our third-generation bionic small amphibious spherical robots have many disadvantages,such as the lack of maneuverability and a small operating range.It is difficult to accomplish underwater autonomous motion control with these robots.Therefore,we proposed a fourth-generation amphibious spherical robot.However,the amphibious spherical robot developed in this project has a small and compact design,with limited sensors and external sensing options.This means that the robot has weak external information collection capabilities.We need to make the real time operation of the robot's underwater motion control system more reliable.In this paper,we mainly used a fuzzy Proportional-Integral-Derivative(PID)control algorithm to design an underwater motion control system for a novel robot.Moreover,we compared PID with fuzzy PID control methods by carrying out experiments on heading and turning bow motions to verify that the fuzzy PID is more robust and exhibits good dynamic performance.We also carried out experiments on the three-dimensional(3D)motion control to validate the design of the underwater motion control system. | Liwei Shi Yao Hu Shuxiang Su Shuxiang Guo Huiming Xing Xihuan Hou Yu Liu Zhan Chen Zan Li Debin Xia | 2020 | Journal of Bionic Engineering2020，17，5： | 4 |
| 3 | A Low Power,High Sensitivity SiGe HBT Static Frequency Divider up to 90 GHz for Millimeter-Wave Application显示文摘A layout and connection optimization for static frequency divider is presented. The layout optimization provides a new circle topology transistors placement and reasonable connection structure, which reduces the parasitic effectively and enables self-oscillation frequency enhancement. Besides, bandwidth enhancement techniques based on a center-tap capacitor in input balun design and inductive peaking in latch design are adopted to improve further high frequency performance with low power consumption. As a proof of concept, design of a divide-by-2 static frequency divider in 0.13 μm SiGe BiCMOS technology is reported. With single-ended input clock signal, the divider is measured to be operated from 40 to 90 GHz. Phase noise measurements of a 90 GHz input clock signal indicate ideal behavior with no measurable noise contribution from the divider. The divider followed by a buffer that can deliver more than-10 dBm output power, which is sufficient to drive succeeding stage. To the author's knowledge, the divider exhibits a competitive power dissipation and the highest FOM among silicon based frequency dividers that operating higher than 70 GHz. | Peigen Zhou Jixin Chen Pinpin Yan Debin Hou Wei Hong | 2019 | China Communications2019，16，2： | 2 |

| 7 | Millimeter-wave wireless communications for home network in fiber-to-the-room scenario显示文摘Millimeter-wave(mmWave)technology has been well studied for both outdoor long-distance transmission and indoor short-range communication.In the recently emerging fiber-to-the-room(FTTR)architecture in the home network of the fifth generation fixed networks(F5G),mmWave technology can be cascaded well to a new optical network terminal in the room to enable extremely high data rate communication(i.e.,>10 Gb/s).In the FTTR+mmWave scenario,the rapid degradation of the mmWave signal in long-distance transmission and the significant loss against wall penetration are no longer the bottlenecks for real application.Moreover,the surrounding walls of every room provide excellent isolation to avoid interference and guarantee security.This paper provides insights and analysis for the new FTTR+mmWave architecture to improve the customer experience in future broadband services such as immersive audiovisual videos. | Chao HE Zhixiong REN Xiang WANG Yan ZENG Jian FANG Debin HOU Le KUAI Rong LU Shilin YANG Zhe CHEN Jixin CHEN | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，4： | 1 |
| 8 | Dose rate effects on shape memory epoxy resin during 1 Me V electron irradiation in air显示文摘The effects of 1 Me V electron irradiation in air at a fixed accumulated dose and dose rates of 393.8,196.9,78.8,and 39.4 Gy s^(-1)on a shape memory epoxy(SMEP)resin were studied.Under low-dose-rate irradiation,accelerated degradation of the shape memory performance was observed;specifically,the shape recovery ratio decreased exponentially with increasing irradiation time(that is,with decreasing dose rate).In addition,the glass transition temperature of the SMEP,as measured by dynamic mechanical analysis,decreased overall with decreasing dose rate.The dose rate effects of 1 Me V electron irradiation on the SMEP were confirmed by structural analysis using electron paramagnetic resonance(EPR)spectroscopy and Fourier transform infrared(FTIR)spectroscopy.The EPR spectra showed that the concentration of free radicals increased exponentially with increasing irradiation time.Moreover,the FTIR spectra showed higher intensities of the peaks at 1660 and 1720 cm^(-1),which are attributed to stretching vibrations of amide C=O and ketone/acid C=O,at lower dose rates.The intensities of the IR peaks at 1660 and 1720 cm^(-1) increased exponentially with increasing irradiation time,and the relative intensity of the IR peak at 2926 cm^(-1)decreased exponentially with increasing irradiation time.The solid-state13 C nuclear magnetic resonance(NMR)spectra of the SMEP before and after 1 Me V electron irradiation at a dose of 1970 k Gy and a dose rate of 78.8 Gy s^(-1) indicated damage to the CH_(2)–N groups and aliphatic isopropanol segment.This result is consistent with the detection of nitrogenous free radicals,a phenoxy-type free radical,and several types of pyrolytic carbon radicals by EPR.During the subsequent propagation process,the free radicals produced at lower dose rates were more likely to react with oxygen,which was present at higher concentrations,and form the more destructive peroxy free radicals and oxidation products such as acids,amides,and ketones.The increase in peroxy free radicals at lower dose rates was thought to accelerate the degradation of the macroscopic performance of the SMEP. | Longyan Hou Yiyong Wu Debin Shan Bin Guo Yingying Zong | 2021 | Journal of Materials Science & Technology2021，，8： | 1 |

| 10 | Research on Silicon-Based Terahertz Communication Integrated Circuits显示文摘With the increasing number of users and emerging new applications, the demand for mobile data traffic is growing rapidly. The limited spectrum resources of the traditional microwave and millimeter-wave frequency bands can no longer support the future wireless communication systems with higher system capacity and data throughput. The terahertz(THz) frequency bands have abundant spectrum resources, which can provide sufficient bandwidth to expand channel capacity and increase transmission data rate. In addition, with the rapid development of silicon-based semiconductor technology,its characteristic size keeps decreasing, and the radio frequency performance of active devices is gradually approaching the performance of III-V semiconductor technology. The realization of THz communication systems based on low-cost, high-stability, and easy-to-integrate silicon-based process has become a feasible solution. This review summarizes the reported silicon-based THz communication systems, as well as the key sub-circuit chips in these systems, including the local oscillator, power amplifier, low noise amplifier, on-chip antenna and transceiver chip, etc. | ZHOU Peigen CHEN Jixin TANG Siyuan YU Jiayang WANG Chen LI Huanbo LU Haiyan YAN Pinpin HOU Debin CHEN Zhe HONG Wei | 2022 | Chinese Journal of Electronics2022，31，3： | 0 |

| 12 | A SiGe W-band frequency tripler with 10.5 dBm output power using harmonic suppression technique显示文摘Dear editor,The rapid development of silicon-based process has motivated great attention in mm-wave applications.Recently,W-band frequencies have become an appealing choice for various wireless applications,such as automotive radar,high data-rate communication,and high resolution imaging.There are two traditional methods to generate local oscillator(LO)singals,implementing voltage-controlled oscillators(VCOs)operating at the desired frequencies directly or low-frequency VCOs followed with a multiplier chain[1–5].The second scheme is more attractive in W-band frequencies for it can relax the designing challenge of the VCO and improve the phase noise. | Huanbo LI Jixin CHEN Peigen ZHOU Debin HOU Wei HONG | 2022 | Science China(Information Sciences)2022，65，4： | 0 |
| 13 | A compact MIMO automotive radar using phase-aligned daisy-chain cascading topology and elevation compensation for 2D angle estimation显示文摘To design a high-performance multiple-input multiple-output(MIMO)automotive radar system with simple hardware architecture,this study presents a daisy-chain cascading design scheme,implementing the two-dimensional(2D)nonuniform antenna array with high-gain antennas for 2D angle estimation.The improvements in the designed radar system are primarily divided into three parts.First,a daisy-chain cascading topology will cause severe phase deviations;hence,we rigorously analyzed the influence of the phase deviations and proposed a low-cost phase-alignment procedure to address this concern.Second,to obtain 2D angular resolution and a longer working range with limited channels,a novel 2D antenna array design principle facilitating the arrangement of high-gain antennas was presented.Third,a new phase compensation procedure was developed to mitigate the deterioration of angular accuracy in the elevation plane.Based on the proposed design scheme,a frequency-modulated continuous-wave(FMCW)radar prototype with two transceiver chips,i.e.,six transmitters and eight receivers,was successfully built.The prototype radar system’s performance was tested through an anechoic chamber and outdoor experiments.Consequently,an angular resolution of 3.5°in azimuth and 12.5°in elevation was featured in the anechoic chamber.Furthermore,using the 2D conventional beam-forming,the outdoor experiment captured high-resolution 2D angular estimation results,thus demonstrating the superior performance of the designed prototype system. | Rui ZHOU Jixin CHEN Yan HUANG Gang XU Debin HOU Bangjie ZHANG Zekun LI Yu XIANG Wei HONG | 2023 | Science China(Information Sciences)2023，66，6： | 0 |
