特征提取是模式识别中最重要的一个部分，这里提供的matlab代码计算一些基本的话音特征，而且，提供了一个简单的基于直方图的特征分类方法的实现。基本的特征包括：特征统计、Energy Entropy Standard Deviation (std)、均值信息熵、过零率检测、频谱衰减等等六个特征(Pattern recognition feature extraction is the most important part, here' s matlab code to compute some basic voice features, but also provides a simple classification method based on histogram characteristics of the implementation. Basic features include: Features and Statistics, Energy Entropy Standard Deviation (std), mean entropy, the zero-rate detection, attenuation, and so the six characteristics of the spectrum)

kalman 滤波器实现，IE算法思想，有源码，有PPT，有文章(realize kalmman filter ,IE program)

虚拟力的无线传感网络覆盖，基于chebyshev的水声信号分析，有较好的参考价值。( Virtual power wireless sensor network coverage, Based chebyshev underwater acoustic signal analysis, There are good reference value.)

Very flexible function, you can create seven segment image of any size

轨道FSK信号发送的小函数。这个函数虽然少，但却是在无数可行方案中选的最优，性能最佳的。在这基础上进行信号处理很不错的。(FSK signal sent from the track a small function. This function, though a small, but they are numerous options in the optimal choice, the best performance. In this based on the signal processing is very good.)
