Title
Single-Point Model Of Mimo-Uwb Indoor Systems Using Time-Reversal Transmission
Abstract
Nowadays, various techniques and systems have been proposed for the implementation of wireless indoor localization systems. Recently, significant focus has been given to Multiple Input-Multiple Output (MIMO) implementations of Ultra-Wideband (UWB) systems, in order 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 x 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. The efficiency of the MATRIP system is demonstrated through simulation results evaluating the average localization error versus the Signal to Noise Ratio (SNR), the Focusing Gain (FG), and the channel capacity.
