Particle-filter-matlab
粒子滤波matlab仿真程序.粒子滤波的基本思想是:首先依据系统状态向量的经验条件分布,在状态空间抽样产生一组随机样本集合,这些样本集合称为粒子;然后根据观测值不断调整粒子的权重大小和样本位置;最后通过调整后的粒子信息修正最初的的经验条件分布,估计出系统状态和参数。该算法是一种递推滤波算法,可以用来估计任意非线性非高斯随机系统的状态和参数。 粒子滤波主要有三步基本操作:采样(从不含观察值的状态空间产生新的粒子)、权值计算(根据观察值计算各个粒子的权值)、重采样(抛弃权值小的粒子,使用权值大的粒子代替),这三步构成了粒子滤波的基本算法。 SIRF(Sample Importance Resampling Filter)算法是粒子滤波的一种基本算法。(Particle filter matlab simulation program)

说明: MUSIC算法
DOA(Direction Of Arrival)波达方向定位技术主要有ARMA谱分析、最大似然法、熵谱分析法和特征分解法,特征分解法主要有MUSIC算法、ESPRIT算法WSF算法等。
MUSIC (Multiple Signal Classification)算法,即多信号分类算法,由Schmidt等人于1979年提出。MUSIC算法是一种基于子空间分解的算法,它利用信号子空间和噪声子空间的正交性,构建空间谱函数,通过谱峰搜索,估计信号的参数。对于声源定位来说,需要估计信号的DOA。MUSIC算法对DOA的估计有很高的分辨率,且对麦克风阵列的形状没有特殊要求,因此应用十分广泛。(DOA (direction of arrival) positioning technology mainly includes spectrum analysis, maximum likelihood method, entropy spectrum analysis method and feature decomposition method. The feature decomposition method mainly includes music algorithm, ESPRIT algorithm, algorithm, etc.
Music (multiple signal classification) algorithm, namely multi signal classification algorithm, was proposed by Schmidt In 1979. MUSIC algorithm is an algorithm based on subspace decomposition. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectrum function, and estimates signal parameters through spectrum peak search. For sound source localization, DOA of signal needs to be estimated. MUSIC algorithm has high resolution for DOA estimation, and has no special requirements for the shape of microphone array, so it is widely used.)
