| 摘 要： | 为了模拟信道误码特性,提出了一种基于均匀分布的伪随机误码发生器的设计方法.该方法不用产生高斯分布伪随机数,只需在均匀分布随机数的基础上设置不同的判决门限即可得到不同的误码率,误码率和误码的位置可控.硬件实验表明,该方法比采用高斯随机数的方案节省约96％的资源.

| Abstract: | This paper presented a method for generating error bits by uniform random numbers which is suitable for digital channel emulator. This method generates error bits by comparing the uniform random numbers with a particular threshold. In this way, the BER can be configured and the positions of the error bits are known to us. It consumes 96% less than that cost by Gaussian random numbers. |

| Keywords: | Gaussian random numbers uniform random numbers bit error rates the inversion principle |
