添加高斯白噪声子程序 内容虽然很简单，但是很有用哦(Add white Gaussian noise subroutine)

用数组产生盲节点和信标节点，比循环产生好许多(Produce blind node and beacon node with arrays, produce much better than the cycle)

一种改进的粒子滤波算法的研究 粒子滤波基本原理，通过改进权重计算、重采样算法， 计算速度得到提高。改进的算法在DSP系统中进行目标跟踪仿真，证明其具有速度快、 精度高的特点(An improved study the basic principles of particle filter particle filter algorithm, recalculation by improving the rights, resampling algorithm to calculate the speed improved. Improved algorithms for object tracking simulation DSP system proved its high speed, high accuracy)

feature extraction using PCA

首先给出了谐波小波时频剖面图检测含噪声信号的微弱奇异成分的方法 然后运用谐波小波时频剖面图方 法分析了碰摩故障仿真信号 最后利用该方法对多个实际汽轮机组动静碰摩故障的真实振动信号进行了分析研 究。结果表明, 谐波小波能够得到其它信号分析方法无法得到的特征, 有效识别机组的碰摩故障。(Harmonic wavelet time􀀁 frequency profile plot is introduced firstly in practice to identify weak singularity in a signal with noise clearly. With this method, emulational signal and vibration data of the rubbing of the large practical turbo-generator units are analyzed successfully, which prove that the method is effectively extract the rubb ing signal feature.)

实现哈弗曼压缩编码的matlab程序。（m文件）(Huffman code)

说明：  对图像进行TA置乱，请根据图像大小自行设定周期。(TA scrambling the image, the image size according to set their own cycle.)

说明：  扩展卡尔曼滤波 用于信号处理, 初学者可是直接仿真使用(Extended kalman filter for signal processing, beginners but direct simulation use)
