DLL architecture for OFDM based VLC transceivers in FPGA [PDF]

2016 10th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2016
This paper addresses the problem of achieving high bandwidth in a DLL design for OFDM based VLC broadcast systems. It describes the implementation of efficient Data Link Layer (DLL) and Forward Error Correction (FEC) modules in a Xilinx FPGA. The proposed DLL aims at furnishing the adequate means to fragment and route both high data-rate (HDR) and ...

BlendVLC: A Cell-free VLC Network Architecture Empowered by Beamspot Blending

IEEE INFOCOM 2021 - IEEE Conference on Computer Communications, 2021
In visible light communication (VLC), the quality of communication is primarily dominated by line-of-sight links. To ensure an appropriate link quality anywhere, beamsteering has been proposed where transmitters (TXs) dynamically steer their beams to create beamspots on the users.
