说明：  构造限制三体问题中平动点周围的halo轨道，实现对太空环境定点观察(Restricted three-body problem Zhongping construct fixed points around the halo orbit, the space environment to achieve the fixed observation)

it is a matlab program used to calculate the FAST FOURIER TRANSFORMS of two given sequences

我在网上找了一份Lee滤波的程序，但实际使用发现是均值滤波，我自己重新写了一份，应该可以使用。(I find the Internet a Lee filter process, but the actual use is found to mean filtering, I re-wrote a, should be used.)

说明：  基于MATLABD的线性二次型最优控制设计(MATLABD based on the linear quadratic optimal control design)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％，不加入噪声，进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)
