Rayleigh Channel Modelling

1．编写一个程序，读取一句英语短语，并将其编制成莫尔斯码 莫尔斯码是世界上最著名的编码机制，是1832年由Samuel Morse创立的，用于电报系统使用。莫尔斯码编码规则如下：①字母、数字和一些特殊符号（如圆点、逗号、分号）用一系列指定的点和线表示；②单词之间用三个空格分开，没有点和线；③编码字母之间用一个空格。 (1 write a program to read a word, English phrases, and programmed into the Morse code Morse Ma is the encoding mechanism of the world s most famous, is in 1832 by the Samuel Morse foundation, used for telegraph system. Morse coding rules are as follows: ① letters, numbers and special symbols (such as dot, comma, semicolon) is represented by a series of specified points and lines the words are separated by three spaces, no point and line the code letters with a space. )
