基带通信中常见噪声的产生方法研究

通常的实验环境中,对数字基带信号的研究是要加入一定的模拟噪声来测量各种参数的。实际中的噪声多种多样,有最简单的均匀白噪声,高斯白噪声,突发随机脉冲噪声以及其他各种分布的随机噪声。通过吸纳或改进传统的产生方法,本文从理论和工程上都给出了产生这些类型噪声的方法,并进一步结合ISA总线设计了基于双RAM的噪声动态产生系统

The study about how to generate noise in base-band communication

In the studying environment of base- band signal, we should assert some noises to the useful signal to measure the commu- nication parameters. Actually, there are many kinds noises .Such as the simple uniform white noise, white Gaussian Noise, sudden pulse noise and other distribution noise. Through absorbing or improving the traditional generating methods, this passage gave the generating methods in the theory and the engineering, and we designed a dynamic noises system which were based of double RAM and ISA bus.
