ANALYSIS OF NONLINEAR DYNAMIC CHARACTERISTICS OF AN IMPACT-UNBALANCED SUSPENDED ROTOR SYSTEM by LIU JunJie, ZHANG LingYun, MA ShaoHui, LAN HaiPeng, ZHANG YouQiang

“…Established an impact-unbalanced suspended rotor system mechanics models, and the dimensionless motion equation of system is deduced, using the fourth order Runge-Kutta method for the numerical calculation of this model, the integrated use of bifurcation diagram, orbit diagram, Poincare section diagram, the axis displacement time history diagram, maximum moment diagram and duty ratio diagram study the dynamic behavior of the system, identify the impact of the rotor, the maximum torque and impact by the proportion of time, and analyzed the speed ratio and the change of the stiffness coefficient of the influence of the nonlinear dynamic characteristics of the system.The analysis results show that the system presents chaotic motion in a certain parameter domain at the medium velocity stage, while the system tends to stable periodic motion in other parameter domains.With the increase of the stiffness coefficient, the chaotic motion region and the maximum moment of the system increase, and the stability of the system decreases.…”

Channel estimation for MIMO SC-FDE systems via time-domain based approaches by LI Dan-ping, LIU Yi, ZHANG Hai-lin

“…Circularly orthogonal sequences were designed for the time-domain channel estimation in MIMO SC-FDE systems.Firstly,Chu sequences were chosen as the base sequences,which were added by cyclic prefix and cyclic postfix to construct circularly orthogonal training sequences.The channel impulse response can be estimated by calculating the cross-correlation between the received signal and the corresponding local sequence.Further,a new training sequence structure was presented,in which the original "long" training sequences were replaced by successive and identical "short" sequences.The corresponding estimation algorithm achieves the same performance as "long" sequences based method.Simulation results show that the proposed algorithms can offer good BER performance even at low SNR,due to the successful interference suppression between the antennas and the decrease in the noise variance.…”

Error performance of multi-branch dual-hop PF cooperative systems by Guangqiu LI, Jiayun DONG, Tao JIANG

“…Design of multi-branch dual-hop phase-only forward(PF)cooperative systems with continuous phase frequency shift keying(CPFSK)modulation needs to determine the number of branch and modulation index.The usual solution of determining the above parameters is the time-consuming and inefficient computer simulation.An efficient solution of determining these parameters is theoretical analysis method.Semi-analytical expressions for the average bit error rate(ABER)of multi-branch dual-hop PF cooperative systems in conjunction with discrimination detection CPFSK over time-selective Rayleigh fading channels was presented.Two cases with and without antenna selection at the relays and maximum-ratio combining(MRC)receive diversity at the destination were considered.The simulation results show that numerical calculation results and simulation results for the ABERs of PF，discrimination detection,CPFSK cooperative systems are consistent and show that the above ABER theory results of CPFSK cooperative systems can be used to design PF cooperative systems.…”
