Abstract
In ground-based wireless positioning,a crucial factor influencing the positioning accuracy is the non-line-of-sight ( NLOS ) error of radio propagation. Before location estimation, determining the radio propagation between transmitter and receiver is LOS or NLOS is an important issue for improving positio-ning accuracy. Firstly, a NLOS identification algorithm based on intersection area measurements is im-proved. Then,for special geometric dilution of precision(GDOP) scene,a NLOS identification algorithm named step by step test algorithm is proposed. This algorithm realizes the NLOS identification by two steps. The LOS measurements are selected by data test( DT) method in the first step,and then the improved inter-section area measurements algorithm is utilized to make the identification in the second step. The simula-tion results show that this algorithm possesses high identification performance under special GDOP scene.关键词
