Deep Learning Based Design of Binary Signalling for Optical Wireless Communication Systems With 2D Receiver

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
We apply a deep learning (DL) technique to binary signalling design for optical wireless communication (OWC) system with a 2D LED transmitter array and an arrayed 2D receiver. It is demonstrated that the DL‐based signalling design algorithm is feasible for OWC system, considering physical channel effect. ABSTRACT Recently, deep learning (DL) techniques
