Abstract
In this paper, design and analysis one of the proposed Optical Orthogonal Frequency Division Multiplexing (OFDM) for Visible Light Communication has been conducted. The chosen design is Generalized LED Index Modulation Orthogonal Frequency Division Multiplexing (GLIM-OFDM), with its proposed scheme that avoid Hermitian symmetry and DC bias. Thus, by utilizing the properties of complex data signal and the bipolar index with spatial modulation Multi Input Multi Output (MIMO) configuration. System generator is used to design the GLIM-OFDM. The design is targeted into Arty Board with Xilinx Artix-7 FPGA. Analysis and comparison are covering in the arithmetic option of unscaled and scaled for its effect on precision, performance, and resource usage. The designed system is proven to work according to theory of operation scheme. To verify that, the reversible design has been designed to ensure the processed data in the transmitter side with the origin data signal. The unscaled option performs slightly faster than the scaled option. Both arithmetic option has same precision of data representation. The GLIM-OFDM design used less resource in unscaled option compared with the design in scaled option.
