Direct-sequence codes based blind synchronization algorithm for UWB systems

引用

The Journal of china Universities of Posts and Telecommunications 2009年第3期16卷 45-51页

作者： QIAO Yong-wei,L Tie-jun,REN Zhi-yuan School of Information Engineering,beijing university of Posts and Telecommunications,beijing 100876,china [a]School of Information Engineering beijing university of Posts and Telecommunications beijing 100876 china

A new blind （non-data-aided） synchronization algorithm based on direct-sequence （DS） codes is proposed for ultra-wideband （UWB） systems. The proposed approach fully exploits prior knowledge of DS codes and bypasses channel estimation. The real-time acquisition is achieved using integrating-and-dumping （I＆D） operation and DS codes matching filter. Because of pseudo randomicity and periodicity of DS codes, both the speed and the accuracy of synchronization are improved significantly. A lower bound on the acquisition probability of the proposed approach is also derived. Simulations confirm performance improvement of the proposed algorithm relative to existing alternatives in terms of acquisition probability, normalized mean square error （NMSE）, and bit error rate （BER）.

Utilization of an H-reversal trajectory of a solar sail for asteroid deflection

引用

Research in Astronomy and Astrophysics 2011年第10期11卷 1123-1133页

作者： Sheng-Ping Gong jun-Feng Li Xiang-yuan Zeng School of Aerospace Tsinghua University Beijing 100084 China

Near Earth Asteroids have a possibility of impacting the Earth and always represent a threat. This paper proposes a way of changing the orbit of the asteroid to avoid an impact. A solar sail evolving in an H-reversal trajectory is utilized for asteroid deflection. Firstly, the dynamics of the solar sail and the characteristics of the H-reversal trajectory are analyzed. Then, the attitude of the solar sail is optimized to guide the sail to impact the target asteroid along an H-reversal trajectory. The impact velocity depends on two important parameters： the minimum solar distance along the trajectory and lightness number of the solar sail. A larger lightness number and a smaller solar distance lead to a higher impact velocity. Finally, the deflection capability of a solar sail impacting the asteroid along the H-reversal trajectory is discussed. The results show that a 10kg solar sail with a lead-time of one year can move Apophis out of a 600-m keyhole area in 2029 to eliminate the possibility of its resonant return in 2036.

Spectral efficient half-duplex relaying with interference suppression

引用

The Journal of china Universities of Posts and Telecommunications 2010年第6期17卷 19-24页

作者： LI Xing-zheng,LIU yuan-an,XIE Gang,CHANG Ling-jun,HAN Xiao Key Laboratory of Universal Wireless Communications,Ministry of Education,beijing university of Posts and Telecommunications,beijing 100876,china [a] Key Laboratory of Universal Wireless Communications Ministry of Education Beijing University of Posts Telecommunications Beijing 100876 China

Two-hop relaying systems suffer spectral efficiency loss due to the half-duplex property of relays. This paper proposes an efficient relaying protocol which can recover the spectral efficiency loss but still work with half-duplex relays. However,there exists inter-relay interference which degrades the performance of the protocol. With this consideration,a power control policy is derived to suppress the interference using game theory,and then an algorithm is given to facilitate distributed implementation. Furthermore,impact of deploying more destination antennas on performance of the relaying protocol is investigated. Simulation results show that,with the power control policy,the proposed relaying protocol can achieve high spectral efficiency.

Climate change scenarios, predicted using the regional climate modeling system of PRECIS (providing regional cli-mates for impacts studies), were used to derive three-layer variable infiltration capacity (VIC-3L) land surface model forthe simulation of hydrologic processes at a spatial resolution of 0.25° × 0.25° in the Haihe River Basin. Three climatescenarios were considered in this study: recent climate (1961-1990), future climate A2 (1991-2100) and future climateB2 (1991-2100) with A2 and B2 being two storylines of future emissions developed with the Intergovernmental Panel onClimate Change (IPCC) special report on emissions scenarios. Overall, under future climate scenarios A2 and B2, theHaihe River Basin would experience warmer climate with increased precipitation, evaporation and runoff production ascompared with recent climate, but would be still likely prone to water shortages in the period of 2031-2070. In addition,under future climate A2 and B2, an increase in runoff during the wet season was noticed, indicating a future rise in theflood occurrence possibility in the Haihe River Basin.

In this article, the governing equations for the unsteady flow of viscoelastic fluid in the eccentric annulus with the inner cylinder reciprocating axially and the expression of the pressure distribution on the wall of the inner cylinder of the annulus are established and derived, respectively, under the bipolar coordinate system. The equations and the expression are solved and calculated numerically using the finite difference method, respectively. The curves of the pressure distribution on the wall of the inner cylinder of the aqueous solution of Hydrolyzed Polyacrylamide （HPAM） are plotted and the influences of annular eccentricity, stroke, and stroke frequency on the pressure distribution are analyzed.

在决策过程中人们通常选择那些使其感到快乐的行为,决策结果与所预测的高兴或悲伤、满意或不满意紧密相连,以往研究发现这类预测即情绪预测存在偏差。本研究以188名中小学生为被试,采用自编情绪评定表和最后通牒游戏范式,对情绪预测偏差与决策的关系进行探索。结果表明青少年在预测对未来事件的情绪反应时存在强度偏差和持续时间偏差,情绪预测的强度偏差和持续时间偏差影响青少年回避或趋向决策。
