Hybrid position and orientation estimation for visible light systems in the presence of prior information on the orientation

Visible light communication (VLC) is seen as a potential access option for fifth-generation (5G) wireless communication (Wang et al., 2014) and (Ayyash et al., 2016) and beyond 5G (Strinati et al., 2019). A reliable VLC system benefits from an …

An over-the-air CFO-assisted synchronization algorithm for TDOA-based localization systems

Time-difference-of-arrival (TDOA) localization systems estimate the difference in propagation delay between a target transmitter and pairs of receivers in order to locate the target. One important requirement is that the receiver nodes should be …

Planar positioning bias due to transmitter and receiver tilting in RSS-based ranging VLP

In this work, a set of general expressions treating both transmitter and receiver tilt in received signal strength based visible light positioning is elaborated. A meticulous approach involving Euler rotations leads to a compact expression for the …

Simultaneous position and orientation estimation for visible light systems with multiple LEDs and multiple PDs

Visible light communication (VLC) is seen as a supplement for fifth-generation (5G) wireless communication in short-range high data rate communication applications [1]. A reliable VLC system relies on an accurate estimate of the position and …

A positioning algorithm for VLP in the presence of orientation uncertainty

As the positioning accuracy of a visible light positioning (VLP) system is highly susceptible to changes in the orientation of the receiver, accurate knowledge of the receiver orientation is required. In practice, the orientation of the receiver is …

On the effect of movement on the localization accuracy in practical wireless networks

The problem of localization involves estimating the position of a user from a number of noisy sensor measurements. In a practical wireless network, these sensor measurements cannot be collected instantaneously and arrive after a certain delay. In a …

Comparison of message passing algorithms for cooperative localization under NLOS conditions

For large wireless networks, there is a need for accurate localization in a distributed manner. Several algorithms have been developed in order to achieve this goal. However, comparing different algorithms is hard because of the use of different …
