整理好的双隐层反向传播神经网络算法例程

對語音作一段前置處理，史的聲音比較圓滑，需要一段語音(right voice for a pre-processing, the history of the voice is relatively smooth, it would take a voice)

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

说明：  一种简单有效的测度熵替代方法——近似熵(approximate entropy)方 法.应用以上方法对Logistic映射复杂度进行了分析.结果表明Lyapunov指数和测度熵的值与复 杂度基本呈线性关系,分维数与复杂度的函数关系尚难确定,且与Lyapunov指数、测度熵之间的关 系也不明确. ( Approximate entropy (ApEn) method is also studied. They are applied to analyze the complexity of Logistic map. The conclusion is that Lyapunov exponent and K-S entropy have approximately linear relation with complexity, while it is difficult to determine the relation between fractal and complexity. )

OFDM的基础代码，种类很多，运行完美，很好实用，欢迎大家下载验证(OFDM-based code, many different types of works perfect, very good and practical, are welcome to download validation)

矩形序贯，是传统序贯法的一种变异，可以处理一些特殊的多普勒回波(Rectangular sequential, is a variation of the traditional sequential method that can handle some special Doppler echo)

有较好的参考价值，采用热核构造权重，仿真效果非常好，从先验概率中采样，计算权重，通过反复训练模板能有较高的识别率，可以实现模式识别领域的数据的分类及回归。

说明：  可以解决随机性问题，是一组不错的程序。在均成功运行。大家可以试一试的。(Stochastic problems can be solved, is a good program. Were successfully run in MATLAB.)
