本文介绍了直接序列扩频系统中数字Costas环的设计与实现，用来实现载波同步的闭环算法(This paper introduces the direct sequence spread spectrum digital Costas loop in the design and implementation to achieve closed-loop carrier synchronization algorithm)

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

MATLAB 的全息代码，图像处理程序，与大家共享，感谢指正。(MATLAB program )

我们假设我们的轨迹从原点（0,0）出发，终点B的坐标是（2,1）。通过Matlab就可以计算出边界条件，最终画出曲线。(We assume that our path from the origin (0,0) starting and ending coordinates of B are (2,1). Matlab can be calculated by boundary conditions, the final draw the curve.)
