digital-processing

介绍了各种数值优化的方法，在通信系统中，很多地方都需要做最优化处理，这本书介绍了详细的优化理论(Introduced a variety of numerical optimization methods, in the communication system, many places need to do one of the optimization, this book presents a detailed optimization theory)

本课题主要研究当信道中的加性噪声为高斯白噪声时，对接收端数字信号的判决带来的影响。 通过实验的手段分析信道无噪声的情况时，对接收端译码译码带来的影响；通过实验的手段分析信道有噪声的情况时，对接收端译码译码带来的影响； 代码可直接运行，包括基带下的误码率仿真，频带下的仿真，以及相互间的对比。界面很好(Signal in channel transfer process, not only by the channel itself, it brought, also influenced by the additive noise, Gaussian white noise is a communication channel additive noise. The main subject of study when the additive channel noise is white Gaussian noise, the impact of digital signal on the receiving end of judgment. By means of analysis of the experimental channel without noise, the impact on the receiving end decoding decoding noisy channel decoder decoding on the receiving end, the impact by means of analysis of the experiment )

matlab解耦合非线性薛定谔方程组，考虑自相位调制、交叉相位调制与四波混频(Matlab solves the coupled nonlinear Schrodinger equations, considering self phase modulation, cross phase modulation and four wave mixing.)

Turbo码仿真程序。有Turbo码的编码，MAP算法，迭代译码，删余和没删余的。(Turbo code simulation program. Turbo codes have coding, MAP algorithm, iterative decoding, censored and no more than delete the remaining.)

VC 中调用MATLAB 程序功能： 为了在vc中调用MATLAB而写的一个简单测试程序 设置路径： 根据MATLAB所在盘而定，例如我的matlab是装在D盘的，所以需要包含的路径为 D:MATLAB6p1externinclude,在工程中设置 需包含的头文件： //matlab中的头文件调用matlab的函数 #include "engine.h" 需要连接的LIB库： D:MATLAB6p1externlibwin32digitaldf50libeng.lib D:MATLAB6p1externlibwin32digitaldf50libmx.lib 支持mx函数 (程序功能： 为了在vc中调用MATLAB而写的一个简单测试程序 设置路径： 根据MATLAB所在盘而定，例如我的matlab是装在D盘的，所以需要包含的路径为 D:MATLAB6p1externinclude,在工程中设置 需包含的头文件： //matlab中的头文件调用matlab的函数 #include "engine.h" 需要连接的LIB库： D:MATLAB6p1externlibwin32digitaldf50libeng.lib D:MATLAB6p1externlibwin32digitaldf50libmx.lib 支持mx函数 )
