Abstract EN
In this paper, a localization scenario that the home base station (BS) measures time of arrival (TOA) and angle of arrival (AOA) while the neighboring BSs only measure TOA is investigated.
In order to reduce the effect of non-line of sight (NLOS) propagation, the probability weighting localization algorithm based on NLOS identification is proposed.
The proposed algorithm divides these range and angle measurements into different combinations.
For each combination, a statistic whose distribution is chi-square in LOS propagation is constructed, and the corresponding theoretic threshold is derived to identify each combination whether it is LOS or NLOS propagation.
Further, if those combinations are decided as LOS propagation, the corresponding probabilities are derived to weigh the accepted combinations.
Simulation results demonstrate that our proposed algorithm can provide better performance than conventional algorithms in different NLOS environments.
In addition, computational complexity of our proposed algorithm is analyzed and compared.
