Kalman filter with a linear state model for PDR+WLAN positioning and its application to assisting a particle filter
Indoor positioning based on wireless local area network (WLAN) signals is often enhanced using pedestrian dead reckoning (PDR) based on an inertial measurement unit. The state evolution model in PDR is usually nonlinear. ...
A Reduced-Order Two-Degree-of-Freedom Composite Nonlinear Feedback Control for a Rotary DC Servo Motor
We study in this paper nonlinear control of a rotary DC servo motor application. To be more specific, we design a reduced-order two-degree-of-freedom (2DOF) composite nonlinear feedback (CNF) controller for a Quanser ...
Semantic Labeling of User Location Context Based on Phone Usage Features
In mobile phones, the awareness of the user’s context allows services better tailored to the user’s needs. We propose a machine learning based method for semantic labeling that utilizes phone usage features to detect the ...
On improvement of transient stage of composite nonlinear feedback control using arbitrary order set point filters
(Institute of Electrical and Electronics Engineers IEEE, 2015-04-01)
This paper studies the generalization of composite nonlinear feedback (CNF) control using arbitrary order set point filters, which focus on the initial stage of the transient response. The set point filters can be used to ...
Modelling of Joule heating based self-alignment method for metal grid line passivation
(MATERIALS RESEARCH SOCIETY, 2014)
A Joule heating based self-alignment method for solution-processable insulator structures has been modeled for the passivation of metal grid lines, for example for organic light emitting diodes or photovoltaic cells. To ...
Motion Model for Positioning with Graph-Based Indoor Map
This article presents a training-free probabilistic pedestrian motion model that uses indoor map information represented as a set of links that are connected by nodes. This kind of structure can be modelled as a graph. In ...
A linear state model for PDR+WLAN positioning
(European Electronic Chips & Systems Design Initiative (ECSI), 2013)
Indoor positioning based on WLAN signals is often enhanced using pedestrian dead reckoning (PDR) based on an inertial measurement unit. The state evolution model in PDR is usually nonlinear. We present a new linear state ...
Software-defined radio prototype for fast-convolution-based filtered OFDM in 5G NR
In this work, we provide first-in-class measurement results for fast-convolution-based filtered orthogonal frequencydivision multiplexing (FC-F-OFDM) processing implemented on a universal software radio peripheral (USRP) ...
Multiplierless filtered-OFDM transmitter for narrow-band IoT devices
In cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) based radio access, the coexistence of different technologies without precise time-frequency synchronization is limited due to high out-of-band emissions. ...
Particle filter and smoother for indoor localization
We present a real-time particle filter for 2D and 3D hybrid indoor positioning. It uses wireless local area network (WLAN) based position measurements, step and turn detection from a hand-held inertial sensor unit, floor ...
