Abstract

The invention discloses an indoor positioning method and system based on signal multipath propagation measurement, and the method comprises the following steps: S1, determining an available signal source and the coordinates of the available signal source from a plurality of indoor signal sources; S2, obtaining the distance from the mobile terminal to the available information source; S3, acquiringa current coordinate of the mobile terminal based on the distance; S4, enabling the mobile terminal to execute positioning display on an electronic map based on the coordinates; and S5, executing training of a channel environment fingerprint analysis engine based on the available information source and the coordinates of the mobile terminal. The technical scheme has the beneficial effects that the precision of measuring the pseudo distance between the mobile terminal and the available information source is high; positioning is realized by adopting public visible base stations and public visible radio signals, such as LBS, WiFi, WiMAX, FM, ZigBee and other fixed base station signals, access authorization of a base station owner is not needed, infrastructure construction investment and energy consumption are not increased, and operation cost burden is not increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an indoor positioning method and system based on signal multipath propagation measurement. Background technique [0002] Global Navigation Satellite System (GNSS, Global Navigation Satellite System) cannot be applied to indoor positioning and navigation. In order to meet the needs of users for indoor positioning, scholars have developed technologies for indoor positioning based on WiFi, Bluetooth, LBS, ZigBee, and UWB. However, the overall positioning accuracy is not high, and can only reach an accuracy of about 5 meters. The progress that can be achieved by using active RFID technology can reach the centimeter level, but there are many problems in actual use, and the cost of global promotion is very high. The fifth-generation communication technology has a certain positioning capability, but the positioning of 5G relies on its dense base stations, and the positi...
