记录我针对数字通信（John.G Proakis）版本学习中编写的仿真程序。 和大家交流共同学习，其中的错误，希望大家指证！ (I look at digital communications records (John.G Proakis) version of the study prepared by simulation program. And to facilitate the exchange of learning, in which the error, hope that means the card!)

这个是本人自己做的一个matlab程序,希望大家可以能用到,2.4.6....32变为灰度(this is the doing of a Matlab procedures in the hope that we can use to be, 2.4.6 .... 32 into gray)

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

描述了OFDM调制解调中的时间同步的算法的方法和相应的代码(Describes a method of time synchronization in OFDM modulation and demodulation algorithm and corresponding code)

蚁群算法实例 使用matlab仿真蚁群算法 找寻最佳路径(Instance of ant colony algorithm matlab simulation ant colony algorithm to find the optimal path)

用matlab求两个向量的相关函数，可以直接执行(Using matlab for the correlation function of two vectors can be directly executed)

说明：  最优化的C程序课件，希望对大家有帮助，还有matlab 的介绍(Optimized C program courseware, we want to help, as well as introduction to matlab)

说明：  有色噪声干扰下多变量系统的辅助模型辨识方法(Colored Noise multivariable model identification method of the auxiliary system)
