电子技术基础 模拟部分（第四版）康光华 本书是电子版，方便大家下载学习(Basic analog electronics part (fourth edition) Kang Guanghua electronic book is to facilitate you to download study)

使用MATLAB实现卷积码的编译码，信源为随机产生数，进行软判决译码(Convolutional code using the MATLAB implementation of the codec, source for the randomly generated number, to soft-decision decoding)

罚函数法是将有约束最优化问题转化为求解无约束最优化问题。在此给出罚函数法的Matlab源程序。(Penalty function method is a constrained optimization problem into solving unconstrained optimization problems. This gives the penalty function in Matlab source.)

图像的压缩编码（JPEG），可以下载看看(Image compression (JPEG), you can download to have a try)

用于图像增强，各种变换的图像增强以及部分空间滤波程序(For image enhancement, transform image enhancement and spatial filtering program)

深刻蚀光栅的色散方程，可以得到有效折射率，(Deep etching the grating dispersion equation can be effective refractive index)

本程序将一随机信号通过瑞利信道产生输出，并用Jakes方法产生单径的符合瑞利分布的复随机过程(This procedure will be a randomly generates an output signal through Rayleigh channel, and use Jakes method produces single-path Rayleigh distribution meet the complex stochastic process)

实现ARX模型阶数的辨识。对给定的真实系统，逐步提高模型阶次，当模型包含真实系统的模型时，模型预测输出与真实系统的输出一致。(System Identification.)

均匀线阵列最大方向性系数综合法，采用特征值分解法。(Uniform linear array directivity factor of the largest integrated method, using eigenvalue decomposition method.)
