Experimental demonstration of deep learning-based HS2PSK-OFDM scheme for optical camera communication

ICT Express
This study proposes HS2PSK-OFDM, a hybrid waveform for vehicular systems using optical camera communication (OCC), which integrates spatial-2-phase-shift-keying (S2-PSK) and rolling-shutter orthogonal frequency division multiplexing (RS-OFDM).

YOLO-OBB and Two-Stage Geometric Correction for RGB-LED Array Optical Camera Communication

Photonics
In Optical Camera Communication (OCC), precise localization of LED arrays under complex tilt conditions is a core challenge for reliable decoding. This paper proposes an OCC reception scheme for RGB-LED arrays that integrates YOLO-OBB rotated object ...

Channel characterization in screen-to-camera based optical camera communication

With the increase in optical camera communication (OCC), a screen to camera-based communication can be established. This opens a new field of visible light communication (VLC) known as smartphone to smartphone based visible light communication (S2SVLC) system.

Impact of Defocusing of the Camera Lens on the Image in Optical Camera Communications

, 2018
In this paper, we propose a theoretical model for the intensity of a blurred image of a light source (LS) due to defocusing in optical camera communications. The blurred image is characterized with four parameters of half power full width, maximum intensity, left and right slope of hazy area and we relate them to the LS, channel, and camera settings ...
