UPF在GPS多路径信号延迟估计中的应用
Application of Unscented Particle Filtering for Time Delay Estimation of GPS Multipath Signal
摘要
Abstract
Multipath signal delay estimation and interference mitigation in satellite navigation are research hotspots.According to the multipath signal nature of close specular reflection, an estimation algorithm based on UPF for the delay time of multipath is investigated.The standard panicle filtering algorithm is presented, and the application of the Unscented Particle Filtering(UPF) algorithm in the estimation of the delay time of multipath is primarily discussed, and the algorithm is deduced in detail.Simulation results verify the effectiveness of this algorithm.关键词
