enhancement

simple experiment on pid along with fuzzy comparision

used for image processing in matlab

图像处理图像处理图像处理图像处理图像处理(image process)

用MATLA实现机器学习中的批处理梯度下降法和随机梯度下降法(Batch gradient descent method and stochastic gradient descent method in machine learning using MATLA)

卷积码的维特比译码器，实现（2,1,7）卷积码解码(vertebi decoder)

说明：  简单的小波包分解和重构单路信号，包括求小波的能量熵(Wavelet Packet Analysis)

说明：  估计随机信号的样本自相关序列。先以白噪声 为例(Random signal is estimated that the sample autocorrelation sequences. First used white noise as an example)

感知器算法的基本思想是，对初始的或迭代中的增广权矢量 ，用已知的训练模式检验它的合理性，当不合理时，对其进行校正，校正方法实际上是最优化技术中的梯度下降法，上传的是用matlab解决感知器问题。(The Perceptron Algorithm The basic idea augmented weight vector of the initial iteration, the known training mode to test it reasonable, unreasonable, its correction, the correction method is actually the most optimization techniques the gradient descent method, upload matlab to solve perception problems.)

产生房间脉冲响应的源代码，在多噪声，多混响的情况下，信噪比很低，信干比也很低，同时伴随着噪声是非平稳的情况。(room impluse response in the nonstation snr sir is very low circumstance)

比较系统的QAM radio仿真程序，包含信道编解码，PAM，QPSK等内容，比较全面(Comparison of QAM radio system simulation program, including channel encoding and decoding, PAM, QPSK and other content, more comprehensive)
