In recent years, location estimation techniques have been attracting much attention because of rapidly growing location based services. This paper proposes a high-performance indoor localization system by combining Wi-Fi access points (AP) with fingerprint-based localization algorithm suitable for indoor environment in terms of estimation accuracy. Although many localization systems utilizing Wi-Fi have been proposed in the previous works, its localization accuracy is not so good because only Received Signal Strength (RSS) is available from off-the-shelf Wi-Fi modules. To utilize other parameters than RSS in localization system, we firstly propose a novel system which can collect and manage various RF parameters. Then, we also describe a novel localization algorithm utilizing Channel Impulse Response (CIR), which is enabled to be collect by using our proposed system. Simulation results validates the effectiveness of our proposed system in terms of localization accuracy. |
