Cooperative location technology in cellular network with NLOS problem
In wireless positioning technology the accuracy of positioning is influenced by NLOS seriously. Base on the measured value of Time of Arrival (TOA), a novel cooperative positioning algorithm with multiple positioning circles is proposed. Firstly, the algorithm estimates the position of one mobile node via TOA localization technology, and then estimates other nodes by using the connection between two nodes. The simulation result indicates that the cooperative positioning algorithm with multiple positioning circles effectively improves the accuracy of location in the environment of cell NLOS and close to the Cramer-Rao bound (CRB).
