description	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.

Η μορφοποίηση δέσης στα συστήματα υπέρ-ευρείας ζώνης (Ultra-Wideband – UWB) αποτελεί ένα τεράστιας σημασίας ζήτημα στον εντοπισμό θέσης εσωτερικού χώρου. Η τεχνική της μετάδοσης αναστροφής χρόνου (Time-Reversal Transmission – TR), σε συνδυασμό με τα UWB, παρέχει έναν μη παραδοσιακό αλλά πολλά υποσχόμενο τρόπο ασύρματης επικοινωνίας με ισχυρή, και ασφαλή επικοινωνία πολλαπλών χρηστών (Multi-User – MU). Πρόσφατα, ιδιαίτερη έμφαση δόθηκε στις εφαρμογές κεραιών πολλαπλών εισόδων-πολλαπλών εξόδων (Multiple-Input Multiple-Output – MIMO) των συστημάτων UWB για την ενίσχυση της ακρίβειας εντοπισμού ενώ εισάγει υψηλή απόδοση επικοινωνίας. Τα κύρια μειονεκτήματα τέτοιων προσεγγίσεων είναι το υψηλό κόστος εγκατάστασης και η πολυπλοκότητα των υπολογισμών λόγω του μεγάλου όγκου δεδομένων προς τελική επεξεργασία. Αυτά τα μειονεκτήματα αντισταθμίζονται με την υιοθέτηση του προγράμματος μετάδοσης της αναστροφής χρόνου (TR), παρέχοντας ταυτόχρονα δυνατότητες κλιμάκωσης και χωρική εστίαση (SF) στο σύστημα. Στη παρούσα εργασία, προτείνεται ένα σύστημα 2X2 Multi-Antenna Time-Reversal Indoor Positioning System (MATRIP) για την παρακολούθηση του κινητού σταθμού Blind Node (BN) σε περιβάλλον εσωτερικού χώρου με μεγάλες απώλειες, με μέτρηση της χρονικής του απόστασης από έναν κόμβο Anchor Node (ΑΝ) σταθερής θέσης. Αυτού του είδους η εφαρμογή ξεπερνά τους περιορισμούς που επιβάλλουν τα συστήματα αυτά, ενώ παράλληλα, κάνουν χρήση του ελάχιστου αριθμού ΑΝ στο σύστημα. 2018-04-18T12:21:39Z 2018-04-18T12:21:39Z 2018-02-19 http://hdl.handle.net/11610/18334 en_US Attribution-NonCommercial-NoDerivatives 4.0 Διεθνές http://creativecommons.org/licenses/by-nc-nd/4.0/ 100 σ. application/pdf application/pdf application/pdf application/pdf application/pdf Σάμος
