Improved Positioning Algorithm Using the Linear Constraints of Scatterer in Two Base Stations
How to restraint non-line-of-sight (NLOS) error is an interesting field. Traditional way to restraint NLOS mainly includes: NLOS identify and NLOS reconstruction. In high multipath environment, these ways can not get good performance. The way proposed by this paper mainly utilizes the linear constraints of scatterer in two base stations to improve traditional way. Simulation results shows improved positioning algorithm can suit for complicate multipath environment and get good positioning precision.
