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)

现代通信原理课程中，在MATLAB中实现二进制相移键控调制程序。(Modern communication theory course, to implement in MATLAB binary phase shift keying modulation program.)

说明：  关于矩阵的VB代码，实现matlab的相应功能。(VB code on the matrix to achieve the corresponding matlab function.)

MATLAB 开发滤波输出系统，可以高低波选择波段，并且为双屏显示(MATLAB development filtered output system, you can choose the level of wave band, and for dual display)

2fsk的解调C语言实现，该程序实现2fsk的解调(2fsk demodulation C language, the program 2fsk demodulation)

Mathematic Pascal problems. it is a lil bit easy with a triangle structure. and the number inside.
