| Summary: | UWB beamforming is of immense importance for indoor localization as well, which has become a hot-topic in UWB indoor applications. The time-reversal (TR) technique, combined with UWB radios provides a non-traditional yet but promising way of robust, secure and multi-user (MU) wireless communications.
Recently, significant focus has been given to Multiple Input-Multiple Output (MIMO) implementations of Ultra-Wideband (UWB) systems, to enhance the localization precision while introducing high communication performance. The main disadvantages of such approaches are the high deployment cost and computational complexity, due to the increased data processing. These facts are compensated by adopting the Time Reversal (TR) transmission scheme, providing scaling capabilities and Spatial Focusing (SF) to the system, at the same time. In this paper, a 2 × 2 Multi-Antenna Time-Reversal Indoor Positioning (MATRIP) system model is proposed to track the mobile Blind Node (BN) in a harsh indoor environment, measuring its time-range from one fixed-position Anchor Node (AN). This kind of implementation overcomes the restrictions imposed by the legacy localization systems, regarding the minimum number of ANs of the system. |
