Channel-Quality-Evaluation-Based Anchor Node Selection for UWB Indoor Positioning
نویسندگان
چکیده
Ultra-wideband (UWB) is a widely used technology in wireless indoor positioning. However, Non-line-of-sight (NLOS) and complex multipath fading introduce positioning errors to the UWB system. In order alleviate influence of non-line-of-sight fading, channel-quality-evaluation-based method proposed this paper. method, qualities channel between unknown nodes anchor are evaluated by weighted equation related impulse response (CIR) characteristics. Anchor with higher quality selected adaptively for The experiments showed that can reduce root-mean-squared error (RMSE) results 40.4% on average 95.78% some strongly degraded cases.

Experimental Evaluation of UWB Indoor Positioning for Sport Postures
Radio frequency (RF)-based indoor positioning systems (IPSs) use wireless technologies (including Wi-Fi, Zigbee, Bluetooth, and ultra-wide band (UWB)) to estimate the location of persons in areas where no Global Positioning System (GPS) reception is available, for example in indoor stadiums or sports halls. Of the above-mentioned forms of radio frequency (RF) technology, UWB is considered one o...
متن کاملA Hybrid TDOA/AOA Positioning Technique for Indoor UWB Systems
A hybrid TDOA/AOA positioning technique for indoor ultra wideband (UWB) systems is presented in this paper. The UWB system is a potential candidate for improving the location accuracy of indoor positioning due to the fine-resolution characteristic of the UWB signals. The hybrid technique consists of extended Kalman filters (EKF’s), which process time difference of arrival (TDOA) and angle of ar...
متن کاملSchemes for Indoor Network Synchronization in Uwb Positioning
Location Positioning is a major technology for ubiquitous computing. A research on Location Positioning using UWB is ongoing. In order to construct an indoor location network, synchronization of base stations is very important. NTP is popularly used as a clock synchronization protocol ranging from LAN to WAN. The Master-Slave scheme, however, is the simplest method for synchronizing an indoor n...
