Implementation of visible light positioning (VLP) on embedded FPGA board

, 2019
In this dissertation, a visible light positioning (VLP) approach based on adapted phase difference of arrival (PDOA) algorithm is implemented on an embedded Field- Programmable Gate Array (FPGA) board. With the support of Xilinx ISE® design suite and python integrated development environment, I have developed an FPGA program and a GUI application on ...

Using Received-Signal-Strength (RSS) Pre-Processing and Convolutional Neural Network (CNN) to Enhance Position Accuracy in Visible Light Positioning (VLP)

Optical Fiber Communication Conference (OFC) 2022, 2022
We propose and demonstrate a received-signal-strength (RSS) pre-processing scheme to mitigate light-deficient-region occurred in visible-light-positioning (VLP) and convolutional-neural-network (CNN) to enhance VLP performance. The RSS pre-processing and CNN model are discussed.

Using DIALux and Regression-based Machine Learning Algorithm for Designing Indoor Visible Light Positioning (VLP) and Reducing Training Data Collection

Optical Fiber Communication Conference (OFC) 2021, 2021
We propose and demonstrate using DIALux software with regression-machine-learning for designing visible-light-positioning (VLP) systems. Besides, the proposed scheme can also reduce the burden of training data collection in VLP systems.

Visible Light Positioning With Visual Odometry: A Single Luminaire Based Positioning Algorithm

IEEE Transactions on Communications
Visible light positioning (VLP) is an accurate and low-cost positioning technique. However, existing VLP algorithms require multiple luminaires or multiple sensors to achieve the desired positioning accuracy, which may not be satisfied in practice.
