DNN-Based Physical-Layer Network Coding for Visible Light Communications
Photonics, 2022 The key difference between visible light communication (VLC) and radio frequency (RF) communication is the former’s line-of-sight (LOS) transmission nature, and hence a relay node has to be adopted for VLC to extend its coverage.
