Abstract

The invention provides an indoor multi-user positioning method based on three-dimensional beam, comprising the following steps: (1) node ends respectively carry out multi-beam polling scanning based on 3D precoding, and send scanning information, wherein the scanning information comprises node id and position information; (2) the mobile terminal detects the received node signal; (3) the mobile terminal carries out three-dimensional spatial position estimation. The beam grouping scanning method based on the multi-user can simultaneously provide good positioning service for a plurality of users,and the positioning efficiency of the indoor positioning system is improved.

Description

technical field [0001] The technical field of indoor positioning of the present invention particularly relates to an indoor multi-user positioning method based on three-dimensional beams. Background technique [0002] With the rapid increase of data services and multimedia services, people's demand for positioning is increasing. Especially in complex indoor environments, such as airport halls, supermarkets, libraries, underground parking lots, etc., it is often necessary to determine whether the mobile terminal or its Indoor location information of holders, facilities and objects. Most of the current positioning algorithms are only researched on wireless two-dimensional networks. However, in practical applications, wireless network nodes are often in a three-dimensional environment. In these cases, it is necessary to provide three-dimensional position information of mobile terminals. Researchers have proposed many methods based on Indoor positioning solutions for radio freq...
