本文通过改进CCITT-图解法来计算数字光纤通信系统接收机的灵敏度,建立了计算机辅助设计的完整程序,可用以较迅速、准确地获取传输距离等工程设计所需的参数。文中举了若干利用本程序计算数字光纤通信系统的实例。
In this paper, CCITT-graphic method is used to calculate the sensitivity of digital optical fiber communication system receiver, and a complete program of computer aided design is established, which can be used to get the parameters of engineering design such as transmission distance more quickly and accurately. This paper gives a number of examples of using this program to calculate digital optical fiber communication system.
