| Abstract: | 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. |
