sin-cos

说明：   This is a collection of MATLAB functions and scripts, and a Simulink model library, useful for designing and analyzing RF communication systems. The block library was originally intended for use in simulating a GPS system. However, the GPS blocks are incomplete and untested due to the abandonment of the GPS project.

本设计通过利用VB 编写用户操作界面和MATLAB 实现后台运算及图形处理的混合编 程的方法，来完成对通信原理仿真系统的开发。设计中采用ActiveX 技术来实现VB 和MATLAB 之间的通信，在VB 应用程序内创建MATLAB ActiveX 对象，实现对MATLAB 的调用，最终 仿真实现信源编码解码、模拟调制解调、数字基带传输、数字调制解调等功能。(This design user interface written using VB and MATLAB computing and graphics processing to achieve the background of mixed programming method, to complete the simulation system for the development of communication theory. Design using ActiveX technology to achieve communication between VB and MATLAB, the VB application, create a MATLAB ActiveX object, call the MATLAB implementation, to achieve the ultimate source codec simulation, analog modem, digital baseband transmission, digital modulation and demodulation functions.)

使用了plot_hht程序包，其使用了三个终止条件，驻留分量的单调性，极值点与零点的个数相差不超过1，还有黄锷1998经典文献提出的 (matlab hht)

异步电机矢控制的Matlab仿真，转速、转矩波形都相当不错，可以直接作为毕业设计的仿真图 使用matlab2010a(Foc of Simulink)

说明：  matlab仿真实现LDPC码编码译码（1/2）(LDPC Decoder for rate=1/2 Min-Sum, Sum-Product, Scaling Min-Sum Layered Decoding for Matlab Code )

光通信中3*3耦合器相位解调的仿真，包括对称解调与非对称解调两种。(Optical Communication 3* 3 coupler phase demodulation of the simulation, including demodulation and demodulation of two symmetric asymmetric.)

MATLAB仿真在电子测量中的应用（程序）.这是这本书的相关程序，可以拿来学习下。(MATLAB simulation in the application of electronic measurement (program). This is the book of the relevant procedures, can be used to learn under.)
