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 moderate data-rate (MDR) service requests while
maintaining a continuous transmission flow. The FEC modules
aims at providing sufficient error correction capabilities with
reasonable computation overheads. Another goal was to develop
these modules under a globally asynchronous locally synchronous
paradigm, ensuring high modularity and performance.
