FPGA Implementation of Bluetooth Low Energy Beacon-Based Indoor Positioning System
2019
In this paper, we described the field programmable gate array (FPGA) implementation of Bluetooth Low Energy (BLE) beacon-based indoor positioning system.Indoor positioning system relies on received signal strength indication (RSSI) from indoor wireless devices.The accuracy of indoor positioning system is easily affected by several signal interference.In order to correct for unstable RSSI values, Kalman filtering technique that has faster and lower error rate is adapted in this system.Also, we adopted the improved trilateration algorithm that has an error range of less than 0.5 m.This system was implemented using Intel's FPGA design tools Quartus II on DE1-SoC board.
