评定数字信号系统是否完善的一个主要指标是信号通过该系统的误码率。在实验室内,用计算机模拟来获得信号通过系统的误码率的方法,是一个节省人力物力,进行系统设计的一个有效的办法。计算机模拟具体地可分为两种方法:(1)逐个码进行比较以获得误码率的方法。该方法是使用计算机来模拟数字信号系统,然后让一数字序列通过该系统,经系统判决后得到一输出数字序列,再将该数字序列
A major indicator of the perfection of a digital signal system is the bit error rate of the signal passing through the system. In the laboratory, computer simulation to get the signal through the system error rate method is a saving manpower and resources for system design an effective way. Computer simulation can be specifically divided into two methods: (1) a method of comparing bit by bit to obtain a bit error rate. The method uses a computer to simulate a digital signal system and then passes a digital sequence through the system to obtain an output digital sequence after system decision. The digital sequence
