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.

Display Light Panel and Rolling Shutter Image Sensor Based Optical Camera Communication (OCC) Using Frame-Averaging Background Removal and Neural Network

Journal of Lightwave Technology, 2021
Optical wireless communication (OWC) has emerged as a complementary or alternative technology to the radio-frequency (RF) communication. OWC based on image sensor, which is also called optical camera communication (OCC) has attracted much attention from industrial and academic societies. Here, we discuss several recent OCC technologies.

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.

Asynchronous scheme for unidirectional optical camera communications (OCC)

2014 Sixth International Conference on Ubiquitous and Future Networks (ICUFN), 2014
This paper proposes software-based scheme for unidirectional communications of OCC system. Proposed scheme based on over-sampling technique will solve fully effects of exposure to the unidirectional OCC system where there is no synchronization. These schemes do not consider mitigating flicker, and then they are suitable for both global shutter and ...
