• 論文の詳細を見る

• This paper presents a study on indoor positioning by D.O.A technology. Direction of incoming signal is estimated by the phase difference between two antenna positions (before moving and after moving). Experiments were carried out in the room (19.2m×33.6m) using 4 fixed points and a mobile terminal. The fixed points were equipped at the corner in the room. 2.4GHz CW was radiated from mobile terminal and received by respective fixed points. Relative phase was measured by a network analyzer. Since multi-path fading caused tolerance in the measured phase, the estimated direction and location also include error. From experiments, the accuracy of the position was around 2m on the average.
