Abstract

The present invention relates to the technical field of positioning algorithms for mobile terminals. More specifically, the present invention provides a method for filtering received signal strength of mobile terminals, which effectively utilizes the location continuity of mobile terminals and utilizes existing data to analyze the mobile terminal's RSSI is used for curve fitting, so as to realize accurate estimation and filtering of RSSI; combined with weight coefficients, the adaptability of the filtering method is improved, and the filtering requirements of mobile terminals in different motion states are met.

Description

A filter method for receiving signal strength of mobile terminal technical field The present invention relates to the technical field of positioning algorithm of mobile terminal, more specifically, to a kind of mobile terminal receiving Signal strength filtering method. Background technique In many mobile terminal positioning systems, based on the received signal strength (Received Signal Strength The positioning algorithm of Indication, RSSI) has the characteristics of fast positioning speed, simple acquisition of RSSI, and no need for additional hardware equipment. point is widely used. In the actual environment, the measured value of RSSI is affected by multipath effect, obstacle occlusion and Doppler effect. Now it is fast fading with fast fluctuation. The fast fading phenomenon of RSSI leads to the low accuracy of the positioning algorithm based on RSSI. It is necessary to filter the measured value of RSSI to improve the accuracy of the positioning algorithm...
