按码流0,1等几率假设改良了光纤数字通信接收机灵敏度计算的Smith方法,给出了一组新的完整的计算公式。用改良后Smith方法构成了光纤通信系统最大中继距离工程设计用紫金Ⅱ微机BASIC程序,演示了不同计算目的的设计实例。
According to the probability of code stream 0,1 and so on, the Smith method which improves the sensitivity calculation of optical fiber digital communication receiver is improved, and a new complete set of calculation formulas is given. With the improved Smith method, the Zijin Ⅱ microcomputer BASIC program for the maximum relay distance design of optical fiber communication system is constructed, and the design examples for different calculation purposes are demonstrated.
