摘要：

With white-light LEDs one can combine lighting and wireless communication functionalities in one source. We investigate feasible transmission rates in a moderate-size office room illuminated with commercially available phosphor-based LEDs. Due to prevalent high signal-to-noise ratios and negligible inter-symbol-interference maximum data rates of 300 Mbit/s are shown to be achievable with the use of pulse amplitude modulation (PAM) or discrete multi-tone modulation (DMT). Also, we present first experiments with white-tight LEDs and demonstrate wireless net data rates of up to 101 Mbit/s.
