Firstly  an equivalent numerical simulation model of CAN bus network is built to derivate the mathematical expression of media access control delay. Secondly  optimization measures are further proposed to improve the data communication real-time. At last  the optimization measures tested by experiments are proved to be correct and effective.

First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   Effects of fabricated error on transmission performance of double screens cross loop slot FSS configuration (EI CONFERENCE) 会议论文  OAI收割 2006 7th International Symposium on Antennas, Propagation and EM Theory, ISAPE 2006, October 26, 2006 - October 29, 2006, Guilin, China 作者:  He B. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 This paper proposes that the inter-layer separation distance (ISD) and the unit cell aligning error (UAE) are used as main variables to study the transmission performance attenuation of the double layer FSS configuration. The numerical analysis model for ISD and UAE was established and also was used to simulate the cross loop slot cell FSS transmission performance by the finite element and periodic moment method program. The double layer cross loop aperture FSS configuration designed was used as the numerical model. As a result of the numerical analysis  it is shown that both ISD and UAE produce insertion transmission loss (ITL) and insertion phase distortion (IPD) directly. Furthermore  ISD results in much loss of the amplitude of the transmitted signal for the FSS than UAE. It is significant for the designer for the multiplayer FSS to assign the fabricated error of the FSS dielectric layers. The UAE introduces the insertion phase variation badly.
