Summary:
In this paper, we study and analyze a DOA-based indoor location positioning method utilizing MIMO wireless LAN system technique. In our method, we estimated wireless LAN terminal location by measured data from arrays of 3 antennas receiver of MIM0 wireless LAN access point and estimated Direction Of Arrival (DOA) of a transmitted signal using MUSIC algorithm, MUSIC with spatial smoothing algorithm and maximum directivity algorithm. Then we introduce several approach techniques to improve the accuracy performance. By using these methods, we can achieve estimation within 1 meter accuracy in indoor 10X10 meter region.
