Article Synopsis
- The study presents a UAV equipped with a light-diffusing fiber that enhances optical camera communication (OCC) by providing a large field of view (FOV) for effective optical wireless communication (OWC).
- The system utilizes the rolling-shutter technique of CMOS sensors to increase the data transmission rate by capturing signal pixel rows individually, leading to significant improvements in data capacity.
- Experimental results indicate that the light-diffusing fiber acts as an "omnidirectional optical antenna," achieving a data rate of 3.6 kbit/s with a pre-error correction bit-error rate of 3.8 × 10.
We put forward and transform the commercially available lighting design software into an indoor visible light positioning (VLP) design tool. The proposed scheme can work well with different deep learning methods for reducing the loading of training data set collection. The indoor VLP models under evaluation include second order regression, fully-connected neural-network (FC-NN), and convolutional neural-network (CNN).

The ODF is a glass optical fiber produced for decorative lighting or embedded into small areas where bulky optical sources cannot fit. Besides, decoding the high data rate rolling-shutter pattern from the thin ODF Tx is very challenging.
