摘要
Abstract
Since the probability density of the measurement error is unknown,the NLOS(non⁃line⁃of⁃sight)noise suppres⁃sion algorithm based on the semi⁃parameter is proposed. On the basis of the fixed label model of flight time,the proposed algo⁃rithm is compared with the traditional method by means of the large⁃scale Monte Carlo method. The simulation results show when the NLOS error is biased Gauss distribution and Rayleigh distribution,the performance of the proposed algorithm is accor⁃dance with that of the traditional method at low NLOS pollution rate,and has strong robustness at high contamination rate. The base station is deployed in combination with indoor and outdoor positioning to test the positioning algorithm in corresponding oc⁃casion. The test results show that the location accuracy of the proposed algorithm is increased by 50% than that of the least square method. The system location error can reach up to 1 m in LOS environment and 3 m in NOLS environment.关键词
