Vth system calculation

标准AM振幅调制方式，ma=0时的标准AM振幅调制(Standard AM modulation, ma = 0 the standard AM modulation)

几个BOC 信号的分析例程，全球卫星导航系统将普遍使用BOC调制信号作为扩频测距信号，BOC信号号自相关函数呈现多个相关峰，传统扩频接收机所用的延迟锁定环（DLL）无法对该信号正确地进行码相位的 (Several BOC signal analysis routines, the global satellite navigation system will generally use the BOC modulation signal as a spread spectrum ranging signal, BOC signal autocorrelation function presents multiple correlation peaks, the traditional spread spectrum receiver with the delay locked loop (DLL ) can not be the signal code phase)

说明：  高光谱遥感图像压缩的lbg算法，十分经典(Hyperspectral remote sensing image compression lbg algorithm, very classic)

SACQPSO优化函数 matlab编写 可以运行 有图仿真(SACQPSO matlab optimization function has prepared plans to run simulation)

说明：  此代码 实现 Seg-Y文件的 读取及显示 功能，在matlab环境下开发的，完整调试通过，且附有详细的程序说明。并附有测试的 seg-y 文件。可以帮助学地球物理的，特别是学 物探 的人员实现 需要的功能！对于想要C++代码的，可以自己看懂后，自己写成C++程序，非常简单，方便！(This code implements the Seg-Y file to read and display capabilities, developed under the matlab environment, complete debugging through, and with a detailed description of the procedures. Together with the test seg-y files. Geophysical science can help, especially school staff to achieve required geophysical features! For those who want C++ code, you can read his post, written in C++ program itself is very simple and convenient!)

多频混合信号，滤波器，最优化低通滤波，切比雪夫带通滤波，最优化高通滤波，matlab(Mixed multi-frequency signal, a filter, a low pass filter optimization, Chebyshev band-pass filter, high pass filter optimization, matlab)

PCM编码,ASK,FAK,DPSK调制与解调(PCM encoding, ASK, FSK, DPSK modulation and demodulation.)

Differential of Functions like Sin , Cos , Tan , Cot and other Functions with Central Oh4 method and calculation of errors Differential with matlab program. Saman Darvish

通过计算和作图，比较4PSK和QPSK这两种不同的编码方式之间的优略，说明发射信号一个是三值的一个是二值的(By calculating and plotting, preferably QPSK, and compare these two 4PSK encoding between different strategies, a description of the transmission signal is a ternary value is two)
