A simple low-sampling-rate receiving scheme is proposed for W-band OFDM-RoF systems. Using the proposed preprocess, aliasing-free subcarriers can be received, and employing the optimized delays to ADCs can achieve the performance insensitive to sampling rate.
We experimentally demonstrate WDM-VLC employing CAP modulation and commercially available RGB-type LED. The record aggregate data rate of 3.22 Gb/s with the BER of less than 10-3 is successfully achieved over >25-cm air-transmission.
We demonstrate 1.1-Gb/s visible light communication (VLC) employing carrier-less amplitude and phase modulation (CAP) and a commercially available phosphorescent white light emitting diode (LED). Optical blue filtering, precompensation, and decision feedback equalization are used to compensate the frequency response of the phosphor-based white LED. Various modulation orders of CAP signals are investigated...
