给定2个点坐标，计算其连线与水平方向的夹角，夹角范围[0,2*pi](failed to translate)

该程序在matlab环境下运行可完成QPSK的调制解调过程，可显示眼图以及滤波后的信号波形。(err)

格型滤波器(lattice filter)Matlab的实现帖子,只用于2阶。请高手看看。不过我还是不会编更高阶的格型滤波器。欢迎一起探讨！zhoujoejx@163.net(lattice filter (lattice filter) Matlab achieve posts. only for the two bands. Look at 19:56. However, I will not write more advanced lattice filter. Welcome to explore! Zhoujoejx@163.net)
