Method for direct self-localization of IR UWB node(s) in indoor scenario

Assessment of Direct Positioning for IR-UWB in IEEE 802.15.4a channels

“…The proposed DPE algorithm is based on a generalization of the pseudoperiodogram approach proposed for TOA estimation. This scheme is of lower complexity than the MUSIC algorithm proposed in [9] and does not require the estimation of the channel coefficients. One advantage of DPE versus two-step positioning is that DPE does not require any calibration, in the sense that two-step scheme requires the proper setting of the threshold value.…”

“…Authors in [8,9] propose applying MUSIC algorithm for solving DPE for self positioning, which requires knowledge of the channel attenuations for the LOS paths. In this paper, we investigate the feasibility of DPE for IR-UWB considering the localization paradigm where the actual processing is performed at the anchor nodes.…”

Method for direct self-localization of synchronous IR UWB node(s) in indoor scenario: Experimental verification

“…MUSIC based method for direct localization in UWB systems based on the concept of stered covariance matrix was proposed in [5]. Method for direct self-localization of synchronous Impulse Radio Ultra Wide Band (IR UWB) Node(s) in dense multipath indoor scenario was proposed in [6] where performances of this method are illustrated by results of simulations. But key challenge is how proposed method works in real physical indoor environment with dense multipath conditions.…”

“…Results of experimental verification of proposed method for self-localization are presented in This work was supported by Serbian Ministry of Science, Education, and Technological Development -DAAD (Germany) collaborative project "'Ultra-wideband (UWB) indoor localization in realistic non-line of sight (NLOS) II. OVERVIEW OF PROPOSED MUSIC-BASED DIRECT SELF-LOCALIZATION METHOD Concept of the system for direct self-localization is proposed in [6] is presented on the fig.1. System is based on the use just one reference UWB node with distributed antenna system and one or many UWB user nodes, time and frequency synchronized with reference node.…”
