| 1 | Dual-turbo receiver architecture for turbo coded MIMO-OFDM systems显示文摘This paper presents a novel architecture of iterative receivers with two layers of iterations for turbo coded multiple-input and multiple-output orthogonal frequency-division multiplexing(MIMO-OFDM)systems,where soft messages are passed not only between the MIMO detector and the turbo decoder,but also between the two component decoders within the turbo decoder.We first derive the factor graph representation of a turbo coded system as a basic building block for developing the iterative receivers.Then,a new soft message passing schedule over the factor graph is proposed,resulting in the proposed dual-turbo receiver architecture(DTRA).In DTRA,the MIMO detector and the turbo decoder work concurrently,and the soft messages for both layers of iterations are updated instantaneously,instead of the block-based exchange of soft messages in the conventional iterative receivers.In so doing,the processing latency can be greatly reduced while low computational complexity can be achieved. | WANG WenJin GAO XiQi WU XiaoFu YOU XiaoHu ZHAO ChunMing WONG Kai-Kit | 2012 | Science China(Information Sciences)2012，55，2： | 5 |
| 2 | Selective electroreduction of carbon dioxide to formic acid on electrodeposited SnO_2@N-doped porous carbon catalysts显示文摘Electrocatalytic reduction of CO_2 is a promising route for energy storage and utilization. Herein we synthesized SnO_2 nanosheets and supported them on N-doped porous carbon (N-PC) by electrodeposition for the first time. The SnO_2 and N-PC in the SnO_2@N-PC composites had exellent synergistic effect for electrocatalytic reduction of CO_2 to HCOOH. The Faradaic efficiency of HCOOH could be as high as 94.1% with a current density of 28.4 mA cm-2 in ionic liquid-MeCN system. The reaction mechanism was proposed on the basis of some control experiments. This work opens a new way to prepare composite electrode for electrochemical reduction of CO_2. | Lu Lu Xiaofu Sun Jun Ma Qinggong Zhu Congyi Wu Dexin Yang Buxing Han | 2018 | Science China Chemistry2018，61，2： | 2 |
| 3 | Quantum-safe cryptography:crossroads of coding theory and cryptography显示文摘We present an overview of quantum-safe cryptography(QSC)with a focus on post-quantum cryptography(PQC)and information-theoretic security.From a cryptographic point of view,lattice and code-based schemes are among the most promising PQC solutions.Both approaches are based on the hardness of decoding problems of linear codes with different metrics.From an information-theoretic point of view,lattices and linear codes can be constructed to achieve certain secrecy quantities for wiretap channels as is intrinsically classical-and quantum-safe.Historically,coding theory and cryptography are intimately connected since Shannon’s pioneering studies but have somehow diverged later.QSC offers an opportunity to rebuild the synergy of the two areas,hopefully leading to further development beyond the NIST PQC standardization process.In this paper,we provide a survey of lattice and code designs that are believed to be quantum-safe in the area of cryptography or coding theory.The interplay and similarities between the two areas are discussed.We also conclude our understandings and prospects of future research after NIST PQC standardisation. | Jiabo WANG Ling LIU Shanxiang LYU Zheng WANG Mengfan ZHENG Fuchun LIN Zhao CHEN Liuguo YIN Xiaofu WU Cong LING | 2022 | Science China(Information Sciences)2022，65，1： | 1 |
