Performance Analysis of 2-D and 3-D Indoor UWB Localization using RSSI

摘要

Indoor Localization is a enormous extent with more relevance and its slight difficult for facing but it has better accuracy. These systems investigate the techniques of wireless indoor positioning system and also many improvements can be done. The positioning algorithm can be done by location metrics like RSSI (Received Signal Strength Indicator) for manipulating the operation evaluation of UWB (Ultra Wide Band) channel model and finally will be displayed for 2-dimension and 3-dimension.The distance can be calculated for trilateration between the Mobile station (MS) and Base station (BS) using RSSI location algorithm. The RSSI shows the accurate manipulation for evaluating the error while comparing to other location metrics like TOA, AOA and TDOA. The error is decreased for the path loss in RSSI and finally, algorithm is also promoted to three-dimension and the estimated locations are filtered to reduce the errors. Also, MSE (Mean Square Error) is also calculated by the use of FSPL (Free Space Path Loss) in simulation and also tracking the objects using Kalman filter.
