| 2 | A NEW HYBRID WAVELET-KALMAN FILTER METHOD FOR THE ESTIMATION OF DYNAMIC SYSTEM显示文摘A new hybrid wavelet-Kalman filter method for the estimation of dynamic system is developed, Using this method, the real-time multiscale estimation of the dynamic system is implemented, and the observation equation established is for the object signal itself rather than its wavelet decomposition. The simulation results show that this method can be used to estimate the object's state of the stacked system, which is the foundation of multiscale data fusion; besides the performance of the new algorithm developed in the letter is almost optimal. | Wen Chenglin Xie Jin Zhou Funa Wen Chuanbo | 2006 | Journal of Electronics(China)2006，23，1： | 2 |

| 4 | Research progress of Ge on insulator grown by rapid melting growth显示文摘Ge is an attractive material for Si-based microelectronics and photonics due to its high carries mobility,pseudo direct bandgap structure, and the compatibility with complementary metal oxide semiconductor(CMOS)processes. Based on Ge, Ge on insulator(GOI) not only has these advantages, but also provides strong electronic and optical confinement. Recently, a novel technique to fabricate GOI by rapid melting growth(RMG) has been described. Here, we introduce the RMG technique and review recent efforts and progress in RMG. Firstly, we will introduce process steps of RMG. We will then review the researches which focus on characterizations of the GOI including growth dimension, growth mechanism, growth orientation, concentration distribution, and strain status.Finally, GOI based applications including high performance metal–oxide–semiconductor field effect transistors(MOSFETs) and photodetectors will be discussed. These results show that RMG is a promising technique for growth of high quality GOIs with different characterizations. The GOI grown by RMG is a potential material for the next-generation of integrated circuits and optoelectronic circuits. | Zhi Liu Juanjuan Wen Chuanbo Li Chunlai Xue Buwen Cheng | 2018 | Journal of Semiconductors2018，39，6： | 0 |
| 5 | State Estimation for Linear Constrained Systems with Unknown Input显示文摘This paper deals with the filtering problem for linear discrete constrained dynamic systems with unknown input. The constraint matrix and constraint vector in this system are allowed to vary in the value and in the dimension. The original full state is separated into two parts,and the estimate of the state is reduced to find the optimal estimate of a singular system. The estimable condition is researched and a recursive estimator for the original full state is presented. A rigorous mathematical induction is given to compare the performance of our approach to that of the existing method without constraint. A numerical example is presented to demonstrate the effectiveness of the new method. | WEN Chuanbo CAI Yunze | 2014 | Chinese Journal of Electronics2014，23，3： | 0 |
| 6 | A NEW HYBRID FORECASTING ALGORITHM AND ITS APPLICATION IN ECONOMIC ANALYSIS显示文摘There exists a great deal of periodic non-stationary processes in natural,social and eco- nomical phenomenon.It is very important to realize the dynamic analysis and real-time forecast within a period.In this letter,a wavelet-Kalman hybrid estimation and forecasting algorithm based on step-by-step filtering with the real-time and recursion property is put forward.It combines the advantages of Kalman filter and wavelet transform.Utilizing the information provided by multi- sensor effectively,this algorithm can realize not only real-time tracking and dynamic multi-step fore- casting within a period,but also the dynamic forecasting between periods,and it has a great value to the system decision-making.Simulation results show that this algorithm is valuable. | Li Shejiao Lv Bing Wen Chuanbo | 2007 | Journal of Electronics(China)2007，24，5： | 0 |
