摘　　要：多径误差包络曲线是评估多径抑制性能的一种重要方法。一般在研究时,该方法采用简单化多径模型。基于简单化多径模型,分析了与环境相关的多径信号模型。在环境相关的多径模型基础上提出了环境相关的多径误差包络曲线,通过软件仿真了该多径误差包络曲线,并分析比较了2种多径抑制性能评估方法。Multipath error envelope curve is an important method for evaluating the performance of multipath mitigation.This method adopts a simple multipath model,based on which the multipath signal model related to environment is analyzed.Based on the environment-related multipath model,the environment-related multipath error envelope curve is proposed,which is simulated by software.Two methods for evaluating the performance of multipath mitigation are also compared.
