关于QPSK调制方法的一个小的仿真，使用matlab做的(QPSK modulation method on a small simulation, using matlab to do)

通过自己学编制的节约里程法matlab程序，已通过实例验证，可行(Compiled by yourself to learn matlab procedures, save mileage law already through examples and feasible)

本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)

说明：  matlab与数学建模--源程序 我是初学者，大家可以参考一下(matlab mathematical modeling- source I am a beginner, we can refer to)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

這是我用scilab寫的高私後向消去與樞軸的程式語法，和高絲後向消去法的差異可見(This is what I write with scilab after the high-private programs to eliminate and pivot grammar, and high-thread after the elimination of the difference can be seen)
