摘　　要：随着通信技术的快速发展,对通信系统的抗干扰性能的要求越来越高。高斯白噪声因其最为常见,且其频谱较宽,干扰的频带范围较大,是一种用于通信系统性能测试的比较理想的干扰源。设计实现了具有较强交织效果的伪随机交织器,对利用线性反馈移位寄存器产生伪随机序列进行交织,使通过B0X——MULLER变换法进行变换产生出高斯随机数的方法得到改进,取得了很好的效果。Along with rapid development of communication technique,the requirement to the anti-jamming function of communication is increasing.Gaussian white noise is the most common noise in communications,its frequency spectrum is wide,and the frequency band scope of interference is big.So it is a kind of fairly ideal interference source that is used to test the communication performance.A pseudo-random interleaver that has stronger effect is designed by adopting interleaving technique.Using this technique,it is a improvement to the former method that gives rise to Gauss Random Number by making use of LFSR and BOX-MULLER transform,and gained very good effect.
