turbo码simulink编码程序，可以用来学如何用c++编写s函数。(simulink code turbo encoding process can be used to learn how to use c++ preparation s function.)

说明：  psat5节点模型，包含故障类型，母线故障以及支路故障(psat5 node model, including fault type, bus fault and fault slip)

用直接周期图法，分别对有噪声和无噪声的信号进行谱估计。(Direct cycle diagram, respectively noise and noise-free signal spectrum estimation.)

本人收集的关于VB与MATLAB混合编程的资料。较详细的描述了二者的接口技术(I collect mixed on VB and MATLAB programming information. More detailed description of the interface technology between the two)

小波包分析提取振动信号中的特征频率，时间序列数据分析中的梅林变换工具，课程设计时编写的matlab程序代码。( Wavelet packet analysis to extract vibration signal characteristic frequency, Time series data analysis Mellin transform tool, Course designed to prepare the matlab program code.)

pheromone levels of terms based on the quality of the best rule among the rules constructed improves the predictive accuracy for some datasets.

说明：  通过二维高斯匹配滤波器来对冠状动脉实现增强，通过多个方向的滤波使得图像的增强效果更好(Matched by two-dimensional Gaussian filter to achieve enhanced coronary artery, through the filter makes the multiple directions better image enhancement)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)

检测概率PD与输入信噪比r的关系（理论曲线） 采样点数：N=100；噪声方差：sigma^2=1 ( Probability of detection PD relationship with the input signal to noise ratio of r (theoretical curves) sampling points: N = 100 noise variance: sigma ^ 2 = 1 )
