本压缩包提供了本人课程教学期间课堂演示的PCM编码与解码、2FSK、2ASK、2PSK调制、基带升弦系统。每个模块达到参数都作了优化，以求获得良好的演示效果，对于学习通信原理课程、本科课程或毕业设计同学非常有用。(The folder include the code for PCM ,2ASK,2PSK,2FSK, base-band raised cosine System. All this was did in the matlab7.0/simulink 。 the parameters in every module prefer in order to get the excellent result .the folder is very useful for students in learning the communication theory and simulink .especially for lesson tasks .)
