Experimental Verification of Applying Active Control Method as Virtual Support for Relief Bridge
Published 2019-01-01“…Test and analysis results show the following: (1) The rotation angle of the cantilever arm can be rotated by the RC servo to appropriate angles to provide adequate upwards resultant force to balance the moving load. (2) The vertical displacement of the bridge can be controlled to close to zero by this proposed NEM. (3) The maximum vertical displacement at the midpoint of a bridge with the NEM control mechanism can be controlled to far below 1/400 of the span of the bridge required by the design criteria. (4) A bridge under the control of an NEM under a low-speed moving load with various control gains achieves fine displacement reduction effects, but the displacement reduction effect for a high-speed moving load with low control gain decreases. …”

A dual mode switching channel estimation algorithm based on SNR decision in high speed railway scenarios
Published 2018-07-01“…A dual mode switching channel estimation algorithm based on SNR decision in high speed railway scenarios was proposed.The algorithm adopted DKL-BEM and LMMSE modelling the channel and estimating the channel under different speed conditions,respectively.The simulation results show that the SNR increased,the performance of the twice channel estimation algorithm based on ICI cancellation became worse than that of the traditional DKL-BEM algorithm,and a cross-point appeared,its value moved towards the small SNR as the speed increased.Through analyzing the parameters and extracting the cross-point values of the two algorithms,the moving trajectory of the cross-point with the speed changing was given.The proposed algorithm can adaptively achieve the switching between two algorithms and improve the applicability and effectiveness of the channel estimation algorithm.…”
