移动通信中多普勒频移的教学方法研究

Research on the Teaching Method of Doppler Frequency Shift in Mobile Communication

移动通信中的多普勒频移是引起无线信道衰落的主要原因。针对现有授课方式中对多普勒频移介绍不足的特点,找到一种快速理解和掌握多普勒频移理论的教学方法,并对该方法进行教学实践。经过实验效果对比,新的教学方法能使学生更好更快地理解相关理论。

The wireless channel fading is mainly caused by the Doppler frequency shift in mobile communication.In view of the insufficient introduction of the Doppler frequency shift in the existing teaching methods,the paper explores a new teaching method and experiment to understand and grasp the Doppler frequency shift quickly.Compared with the experimental results,the relevant theories can be understood faster by the new teaching method.
