Weather Independent Positioning of MS Using Power Slope Patterning Algorithm via One BS
Avra Bhattacharjee, Md. Rafi Islam, Muhammad Ahsan Ullah · 2019
Numerous methods have been applied to accurately determine the location of a mobile station (MS), of which, most of them require weather dependent parameters. An efficient method of positioning and mapping a mobile station in varying weather conditions, without the use of Global Positioning System (GPS); operable using the preestablished infrastructure is proposed. Another advantage of this system is that, only one base station (BS) is utilized. The uplink control channel power from a mobile station received by a base station determines the power to be transmitted to that user. With the change of weather condition, the power data also changes. However, the collective power level changes uniformly; allowing their slopes to remain constant in any case. Extracting the slope of the plot eludes the system from power amplitude dependency, henceforth making this system exclusive to weather change.
