直接序列扩展频谱的源代码，用于产生直接序列，可进行现行的编码工作，用于无限通信中 (Direct sequence spread spectrum of the source code, used to produce direct-sequence, it can conduct the work of the existing coding for unlimited communication)

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)
