Analysis of Optical Camera Communications for Terminal Jiggle With Quality of Service Guarantees

Journal of Lightwave Technology, 2023
Although Optical Camera Communications (OCC) has carved out a space in sixth-generation(6G) communications, building a theoretical analysis model for OCC remains an open question. Hence, we propose the analytical models for OCC systematic evaluation with

Wide Field-of-View (FOV) Light-Diffusing Fiber Optical Transmitter for Rolling Shutter based Optical Camera Communication (OCC)

Optical Fiber Communication Conference (OFC) 2022, 2022
We propose a wide field-of-view (FOV) light-diffusing-fiber (LDF) transmitter optical-camera-communication (OCC). Pixel-row-per-bit-neural-network (PRPB-NN) is employed for rolling-shutter-pattern decoding. PRPB-NN provides efficient decoding at 360o around LDF circumference and 160o Rx rotation-angle at 2100-bit/s.

Z-Score Averaging Neural Network and Background Content Removal for High Performance Rolling Shutter based Optical Camera Communication (OCC)

Optical Fiber Communication Conference (OFC) 2021, 2021
We propose and demonstrate using Z-score averaging neural-network (Z-NN) and background-content-removal (BCR) to mitigate the inter-symbol-interference (ISI) in camera-communication (OCC). 950-bit/s over 3-m free-space transmission is achieved.

Using Pixel-per-bit Neural Network for Two Rolling Shutter Patterns Decoding in Optical Camera Communication (OCC)

2021 30th Wireless and Optical Communications Conference (WOCC), 2021
Optical wireless communication (OWC) has received increasing attention recently. One application of OWC uses image sensor as optical receiver, which is known as optical camera communication (OCC). Rolling shutter mode in OCC allows data rate higher than the camera frame-rate operation.

Non-line-of-sight optical camera communications based on CPWM and a convolutional neural network.

Applied Optics, 2023
Non-line-of-sight (NLOS) optical camera communications (OCC) exhibit greater link availability and mobility than line-of-sight links, which are more susceptible to blocking and shadowing. In this work, we propose an NLOS OCC system, where the data signal
