Abstract
Optical wireless communications using a light-emitting diode are unlikely to cause electromagnetic interference to electronic devices, then they are expected to be used in hospitals. Based on a communication scheme realizing data multiplexing and error correction coding simultaneously using discrete Fourier transform over finite fields, this study proposes a Reed-Solomon coded multiplexing scheme for optical wireless communications and shows evaluations of transmission characteristics. The scheme removes background light interference using a cancellation technique. And multiplexing user information data into a multiplexed symbol stream over the finite field contributes to symbol transmission with low peak-to-average power ratio characteristics.
