摘要
In GPS navigation, distortion of the delay and phase of the received signal due to multipath propagation can degrade seriously the position estimation. In some applications such as aircraft landing, detecting the occurrence of multipath can be as important as mitigating its effect on the pseudodistance. This paper proposes deterministic particle filtering for joint multipath detection and navigation parameter estimation. The efficiency of the proposed method is illustrated by numerical simulations.
