摘要

This letter presents the desigo of a Gbit/s real-time light-fidelity transceiver based oil field programmable gate array (FPGA). We exploit discrete Fourier transform spread orthogonal frequency division multiplexing as a modem scheme, while wavelength division multiplexing technology is employed to enhance the data rate by commercial red-green-blue light emitting diodes. The transceiver achieves a peak rate of 1.34 Gbit/s over 3.5 m of free space below the forward error correction limit of 3.8 x 10(-3). This letter also considers the requirement of mapping the proposed FPGA design into very large-scale integration.
