16-QAM modulation and demodulation

在FFT后信号的频率往往与谱线不相重合，而在两条谱线之间。为了要求得信号的频率、幅值和初始相角，必须要使用修正法来完成。这里给出一种修正法。(After the signal in the FFT frequency spectrum often do not coincide, and in between the two lines. Request for a signal frequency, amplitude and initial phase angle, we must use to complete the Amendment Act. Here are a Amendment Act.)

说明：  各种各样的不同代码源打包，都是经过运行的，绝对可以使用。(A variety of different source code packages are run through, and absolutely can be used.)

说明：  QASK的实现。用matlab程序 通信调制基础(QASK implementation. Modulation based communication program with matlab)

这是永磁同步电机的直接转矩控制，仿真结果表明性能良好，值得大家借鉴。(This is a direct torque control of permanent magnet synchronous motor, the simulation results show good performance, it is worth learning from.)

协作通信的两种协作方式AF、DF的相关文档和独立编写的仿真程序，可用于比较两种方式下的误码性能(Collaboration of the two types of communication modalities for collaboration AF, DF and documentation prepared by an independent simulation program can be used to compare two methods of bit-error performance)

说明：  粒子群算法(pso)标准测试函数验证程序。在一个m文件中包括了目前文献中用于验证的7个标准测试函数(Ackley等)、三维动态显示，粒子过分集中时打散等功能。旨在为学习和研究者pso算法的同仁提供一个功能较为完备、简单易懂的标准版本，对于初学者可以通过此程序快速的实现入门，以便将更多的精力投入到深层次的研究中去！同时愿与所有致力于此的朋友共同探讨pso算法的改进与应用方面(如多目标、动态系统等)的经验。(PSO algorithm (PSO) standard test function verification process. M in a document, including the current literature is used to validate the seven standard test function (Ackley), 3D dynamic display, and the over-concentration of particles scatters when the function. Designed for researchers to study and colleagues at the PSO algorithm to provide a more complete functional and easily understood standard version, for beginners through this program to achieve rapid entry. in order to be more energy into depth study! While willing to work with all the friends here to discuss PSO algorithm improvements and applications (such as multi-target, Dynamic systems, etc.) experience.)

VC与Matlab的混合编程方法及其应用 详细介绍了VC与Matlab混合编程的方法和实例，适合初步接触混合编程的人使用。(Mixture of VC and Matlab programming and application details of the VC and Matlab programming methods, and case mix for the initial contact with mixed programming to use.)

此程序下载后需解压才能使用，该程序代码质量高，简单易懂。(download this program will require decompression can be used, the code of high quality, simple and understandable.)
