Identification amp; precise estimation of signals in bimodal noise 双模噪声中信号识别与精确估计
We analyze the statistical characteristics of bimodal noise thoroughly, that provides theoretical basis for models transformations & precise estimations of noise & signal parameters 深入分析了双模噪声模型的统计特性,为模型转换及精确估计噪声和信号参量提供了理论依据。
On the estimation of signal & bimodal noise parameters, some foreigners give out approximate estimation, which is applicable only on some condition; we give out the precise estimation 对于双模噪声与信号参量的估计,国外给出了近似估计,只在一定条件下适用:本文给出了精确估计。
(2 ) the response characteristics of wind-induced vibration under uncertain parameters were analyzed, which suggested a simplified method for evaluating mean and standard variance of acceleration responses . compared with the results given by a form and fosm method, the suggested methods can give a more precise estimation (2)研究了随机参数作用下的结构风振均方根加速度响应的分布规律,给出了直接估计均方根加速度响应均值和方差的解析表达式。
The noise estimation theory of the gps / ins integrated navigation system and the error analysis is are systematically discussed in this dissertation . at first the paper briefly introduce the error of the integrated system and the cause of the error, and give an estimation model of the error . in order to solve the precise estimation of the error using artificial neural network, then an artificial neural network model is discussed 本论文首先介绍了gps惯性组合导航系统的误差和误差模型,综述了gps和惯导系统的误差和误差来源,给出了这两种导航系统的误差方程,讨论了导航系统中常用的数据处理方法?卡尔曼滤波,给出卡尔曼滤波的基本方程,深入研究了卡尔曼滤波在组合导航系统数据融合中的应用。
The progress of the venture capital project was traced, the information of market and technology was collected, and the developing directions of financing, technology and organization were monitored strictly, so more losses could be avoided by precise estimation and terminating the project in time for some projects with terrible prospects . e 通过对风险投资项目的进展进行跟踪预警,利用搜集到的来自于市场、技术等方面的信息,严密监测财务、技术、组织方面的发展动向,对一些前景黯淡的项目做出及时准确的判断并及时地终止投资可以避免更大的损失。
