UWB positioning enhancement using Markov chain in indoor NLOS environment被引量:3
《The Journal of China Universities of Posts and Telecommunications》2020年第4期54-58,98,共6页Li Shaoxian Lii Fan Wang Chengrui Hou Yanzhao 
supported by the National Natural Science Foundation of China ( 61701042)。
The accuracy of the positioning system in indoor environment is often affected by none-line-of-sight(NLOS) propagation. In order to improve the positioning accuracy in indoor NLOS environment, a method used ultra-wide...

Improved positioning algorithm based on two step least square in NLOS environments被引量:1
《The Journal of China Universities of Posts and Telecommunications》2011年第5期58-63,共6页WU Shi-xun LI Ji-ping-yin LIU Shou 
supported by the National Natural Science Foundation of China (60572117);the Scientific Research Foundation for the returned Overseas Chinese scholars, State Education Ministry
Non-line-of-sight (NLOS) propagation is a major source of error for accurate time-of-arrival (TOA) location estimation. The two-step least square (LS) method, which does not need any information about the distri...
