Anchor Pair Selection in TDOA Positioning Systems by Door Transition Error Minimization
Marcin Kolakowski, Jozef Modelski
This paper presents an adaptive anchor pairs selection algorithm for UWB (ultra-wideband) TDOA-based (Time Difference of Arrival) indoor positioning systems. The method assumes div…
The Use of MEMS Accelerometers for Remote Activity and Living Parameters Monitoring
Natalia Osiadala, Marcin Kolakowski
In the paper a ballistocardiographic sensor for remote monitoring of activity and vital parameters is presented. The sensor is mainly intended for use in monitoring systems support…
Comparison of Extended and Unscented Kalman Filters Performance in a Hybrid BLE-UWB Localization System
Marcin Kolakowski
The paper presents a comparison of performance of two Kalman Filters: extended Kalman filter (EKF) and unscented Kalman filter (UKF) in a hybrid Bluetooth-Low-Energy-ultra-wideband…
A Hybrid BLE/UWB Localization Technique with Automatic Radio Map Creation
Marcin Kolakowski
Localization systems intended for home use by people with mild cognitive impairment should comply with specific requirements. They should provide the users with sub-meter accuracy…
Detection of direct path component absence in NLOS UWB channel
Marcin Kolakowski, Jozef Modelski
In this paper a novel NLOS (Non-Line-of-Sight) identification technique is proposed. In comparison to other methods described in the literature, it discerns a situation when the de…
Kalman filter based localization in hybrid BLE-UWB positioning system
Marcin Kolakowski
In this paper a concept of hybrid Bluetooth Low Energy (BLE) Ultra-wideband (UWB) positioning system is presented. The system is intended to be energy efficient. Low energy BLE uni…
