| 摘 要： | 本文根据用CCITT改良法计算光纤接收机灵敏度的要求,使用FORTRAN 77语言,编写了一个计算灵敏度和最佳增益的计算机通用程序.该程序可以同时对使用不同输入波形(高斯波和矩形波)、不同检测器(APD或PIN)、不同前置放大器、不同线路码型的接收机灵敏度及最佳增益进行计算,并对实际光纤接收机作了验证.

| Abstract: | So far, the calculation about the sensibility and optimal gain of digital optic receiver is all made by diagram which needs to calculate a number of data and influences the accuracy and speed. According to the CCITT recommendation about calculation of the sensibility of optic receiver, a general computer program of calculating the sensibility and the optimal gain is compiled with FORTRAN 77. The program can calculate separately sensibility and optimal gain of the receiver which has the different input waveform (Gauss wave, retangular wave), detector (APD or PIN LED), amplifier and line code. The program has been verified by actual optical receiver. |
