多基站下基于信號(hào)到達(dá)時(shí)間的室內(nèi)三維定位
[Abstract]:The location technology of time of arrival (TOA) based on radio signal is studied. Firstly, the functional relationship between the measured value of TOA and the real value is established, and the terminal location and noise estimation are realized by solving the nonlinear least square problem with penalty terms, and the Alternating Iterative Reweighting (AIR) algorithm is proposed on the basis of previous research. Secondly, the geometric position between the base stations is used to select and locate the least adaptive base station according to the information of each terminal, and the trajectory prediction of the terminal motion is realized by combining the physical characteristics. Finally, according to the communication radius of the base station, the locatable terminal is selected, and the relationship between the positioning accuracy and the average connection degree of the terminal is established.
