摘要
克服高速移动带来的多普勒效应是移动通信系统一个必须解决的问题。该文首先介绍了多普勒效应的原理，进而分析了多普勒效应在移动通信中对载频的的影响，最后运用MATLAB语言和simulink模块实现了在声频范围内多普勒效应的仿真。
To overcome Doppler effect caused by the high-speed mobile is a problem which the mobile communications system must be solved. This paper first introduces the principle of the Doppler effect, and then analyses the impact of the Doppler effect in the mobile communications to carrier frequency. Finally, the use of MATLAB language and Simulink module simulates the Doppler effect.in the audio range of frequency.
