混合定位算法在复杂室内环境下的应用研究
Applied research of hybrid positioning algorithm in complex indoor environments
摘要
Abstract
This paper investigated 3D positioning in an indoor line of sight (LOS)and nonline of sight (NLOS)combined en-vironment.It was a known fact that time-difference-of-arrival-(TDOA-)based positioning outperforms MS other techniques in LOS environments;however,multipath in an indoor environment,especially NLOS multipath,significantly decreased the accu-racy of TDOA positioning.On the other hand,received-signal-strength-(RSS-)based positioning was not affected so much by NLOS multipath as long as the propagation attenuation could be correctly estimated and the multipath effects had been compen-sated for.Based on the fact,it proposed a hybrid weighted least square (HWLS)RSS /TOA method for target positioning in an indoor LOS /NLOS environment.It implemented the identification of LOS /NLOS path by using Nakagami-m distribution.An ex-periment verifies our proposed scheme.关键词
