| 摘 要： | 对无线通信电磁干扰进行仿真研究具有重要实用价值,可以应用到多种仿真系统中。针对无线通信所受到的电磁干扰情况,对电磁干扰进行了分类,引入各类噪声模型,并以调幅噪声干扰调频信号为例论述了电磁干扰的基本原理。并从电磁干扰效果的角度出发,通过MATLAB软件中数据采集工具箱采集语音信号,同时用MATLAB中的函数生成或数据采集工具箱采集的方法产生离散噪声数据,之后将噪声数据与语音数据叠加,实现对无线语音通信电磁干扰的仿真。最后采用图形方式演示了仿真效果,证明了该方法可行性。 |

| Abstract: | It is of important practical value to simulate EMI for wireless phonic communication,and it can be applied to many kinds of simulation systems.In view of the EMI on wireless phonic communication,this paper classifies the EMI,and introduces some noise models,then takes EMI between FM and AM signals as an example to discuss the EMI theory.Starting from the EMI effect,the paper introduces an EMI simulation method of how to sample voice signal with Data Acquisition Toolbox,and how to produce discrete noise data... |
