中文摘要: 为了提高无线传感网络的性能，采用离散多径信道的可变延迟模型分析与计算机仿真结合的方法研究了影响无线传感网络信号传输的多普勒效应。仿真结果表明，多普勒效应对无线传感网络传输的信号电平产生干扰，对包络幅度产生不同程度的衰落，多普勒频移越大衰落越深。
Abstract:For the sake of improving the performance of Wireless Sensors Networks (WSN), Doppler Effect on the signal transmitted in WSN is discussed through the combination of mathematic model and computer simulation. The Simulation shows that Doppler Effect produces level interference and Envelope Magnitude’s fading on signal transmitted in WSN, and fading is more serious if the Doppler Shift is larger.
