SC-CFDMA uplink symbol synchronization method based on multi-rate satellite-ground loop by Dan DING, Nai-ping CHENG, Yu-rong LIAO

“…SC-CFDMA(single carrier code and frequency division multiple access) system,whose synchronization is more difficult than that of common orthogonal multi-carrier systems,requires the symbol synchronization to achieve a chip-level precision.Therefore,a synchronization method based on multi-rate satellite-ground loop is proposed.This method extends the closed-loop control on the non-sampling points of the loop through raising the control rates of some loop components,so as to promote the adaptability to users with different speeds.Besides,the state-space equations of the loop and related components are derived.The Matlab simulation results show that,even in GEO satellite system,the synchronization method proposed can adjust the SC-CFDMA uplink symbol timing errors between several supersonic users within chip-level duration,thus providing stable communication.…”

On the Convergence of a Smooth Penalty Algorithm without Computing Global Solutions by Bingzhuang Liu, Changyu Wang, Wenling Zhao

“…Under a generalized Mangasarian-Fromovitz constraint qualification condition (GMFCQ) that is weaker and more comprehensive than the traditional MFCQ, we prove that the sequence generated by this algorithm will enter the feasible solution set of the primal problem after finite times of iteration, and if the sequence of iteration points has an accumulation point, then it must be a Karush-Kuhn-Tucker (KKT) point. …”

STUDY ON DYNAMIC BALANCE OF AEROENGINE FLEXIBLE ROTOR BASED ON TRANSFER FUNCTION by ZHANG Ying, WANG KunPeng, MA Liang

“…The experiment and simulation results show that the transfer function method has better balance effect than the influence coefficient method, which can effectively reduce the vibration of unbalanced rotor and avoid the disadvantage of the influence coefficient method in starting the rotor several times. It has a good application prospect in the maintenance of aero-engine.…”

Carrier initial phases estimation for single-channel adjacent-frequency mixture of digitally modulated signals by Yong YANG, Yi-ming GUO, Hai-xin WANG, Hua PENG, Dong-ling ZHANG

“…For single-channel mixture of adjacent-frequency digitally modulated signals which have the fixed frame length and sync codes in non-cooperative satellite communications,a carrier initial phases estimation algorithm which can be applied to both low-order and high-order digitally modulated mixtures was provided according to the differences of parameters in the source signals.The sync data eliminated the frequency offset was added in the interval of frame length firstly,then timing synchronization was accomplished for the added result in terms of power maximization rule,thus the initial phases information was derived.Moreover,the modified Cramer-Rao bound (MCRB) of carrier initial phases for single-channel mixture of adjacent-frequency digitally modulated signals was derived for comparison.Simulation results show that,difference between estimation performance of the proposed algorithm and MCRB becomes smaller with the increase in the number of added frames.…”

Multi-objective cloud workflow scheduling algorithm based on grid variance by Xiaoan BAO, Yundi CAO, Na ZHANG, Junyan QIAN, Jianwen CAO

“…Multi-objective cloud workflow scheduling algorithm based on grid variance and the strategy of bad particles self-learning were presented.Firstly,the characteristics of task scheduling was token into consideration,and particle encoding was discredited.Secondly,the strategy of mapping Pareto optimal workflow scheduling set to self-adaptive grid coordinate system,and calculating the grid distribution value of each Pareto optimal solution was used.Thirdly,grid variance was adopted to evaluate the diversity of current Pareto front and dynamically adjust evolution strategies.Finally,the concept of being dominated times was introduced into bad particles self-learning strategy for filtering out bad particles in population.The simulation experiment shows that workflow scheduling solution set by this algorithm is better than the MOPSO algorithm on both IGD and S performance indexes,and the optimal value is superior to the ε-FDPSO and NSGA-Ⅱ algorithm.…”
