本文最后对最大后验概率估计法进行了研究,给出了最大后验概率估计法的原理、方法和步骤。 - This paper studies 3 kinds of algorithms : the viterbi algorithm , multiresolutional algorithm based on wavelet transformation and bayesian bootstrap algorithm . the viterbi algorithm is based on the hidden markov model theory and it is a kind of map estimation , this paper studies this algorithm and puts up an algorithm that suits for filtering in the presence of interference . multiresolutional algorithm takes full advantage of multiresolutional data , we can see it has a better filtering ability than the traditional filtering methods ; bootstrap algorithm is a recursive bayesian estimation , it describes the probability density function by the samples , so it can be used to nonlinear non - gaussion filtering , the simulation result of the two groundings is presented
Viterbi算法以隐马尔可夫理论为基础，是一种最大后验概率估计方法，本文对该算法进行了研究，给出了一种适合于非高斯干扰条件下的滤波方法；多分辨分析方法充分利用到了多分辨率测量数据所包含的信息，从仿真结果中可以看出，该方法的滤波精度要高于传统的滤波算法；自主滤波方法是一种递推贝叶斯估计算法，它利用采样点来描述目标状态的概率密度函数，因而适用于非线性、非高斯条件下的滤波，本文分别对这两种情况下的滤波进行了仿真。 - There are mainly two type of algorithms used for spatial spectrum estimation : one is those based on bayesian maximum likelihood method , like the ml ( maximum likelihood ) algorithm , maximum entropy method and etc . , the others are based on the spatial decomposition or projection of correlation matrix , this kind of algorithm include vector characterization method , music ( multiple signal classification ) algorithm , projection matrix method , etc . music is a classical spatial spectrum estimation algorithm that has a super high resolution and is widely used today , however , it cannot estimate doa of signals that are correlated
空间谱估计的算法大致分两大类:一是基于极大似然估计和最大后验概率估计统计理论的算法,包括:极大似然估计法( ml ) 、最大熵法等;另一类是基于对协方差矩阵进行子空间分解或投影的算法,包括:矢量特征法、多重信号分类法( music ) 、投影矩阵法等。其中, music法是一种经典的空间谱估计主流算法,具有超强的分辨性能,但它无法实现对相干信号进行测向分辨。
