查询词典 mean type

The main research contents and results are given as follows:(1) Principles and characteristics of different types of polarization controllers are analyzed, the compare of the difference of these polarization controllers are discussed based on them, drawn a conclusion that the polarization controller which based on squeezing fiber and has variable delay quantity are suitable for high speed optical communication system.(2) The reset principle of the typical four channel polarization controller which is based on squeezing fiber is analyzed, and the design of its concrete reset scheme is given based on them. The reset process and the corresponding operation list are given in detail.(3) The systematical experiment is made when the typical four channel polarization controller is put into the PMD compensator. The experiment result showed that the channel which needs reset can efficiently return to the mean place, and the effect of reset was good, it didn't cause any badness infection on PMD compensation.(4) A new type optical signal time-domain depolarizer is given, and a new PMD compensate method is given based on it.

由此得出延迟量可变型光纤挤压型偏振控制器适用于高速光通信系统的结论；(2)具体分析了典型的四通道光纤挤压型偏振控制器的复位原理，并在此基础上对其进行了具体复位方案的设计，给出了各种情况下的详细复位流程和相应的复位操作列表；(3)将四通道光纤挤压型偏振控制器应用于偏振模色散补偿器中进行系统实验，实验结果表明，需要复位的通道能有效地回到中间值，复位效果良好，且复位未对PMD补偿产生不良影响；(4)设计了一种新型的光信号时域退偏器，并基于该退偏器提出了一种新型的偏振模色散补偿方法。

Under the assumptuion that the lower bound of the density of the observed nonlinear AR (1) time series is known, we prove that the nonlinear wavelet estimator of the conditional mean function g, which is similiar with the one introduced in Chapter 2, still has the same good adaptive properties for this kind of nonlinear AR (1) series on account of the moment inequalities and exponential type inequalities for strong mixing processes.

在假设观测序列的的密度函数的下界已知的条件下，我们利用关于强混合过程的矩不等式以及指数型不等式证明了类似于上一章的小波估计对于非线性AR（1）模型中条件均值函数的非参数函数估计仍然具有优良的自适应性质，并同样给出了数值模拟的结果分析。
