Channel estimation is conceived for optical wireless scattering channels associated with laser diode transmitters and photon-counting/photomultiplier tube receivers. The proposed channel estimation approach consists of two stages, namely, of the estimation of the channel tap second-order moments followed by the estimation of the channel taps based on the estimate of second-order moments. In the first...

In visible light communication (VLC) networks, signals from densely deployed light sources strongly interfere with each other. Proper interference management is expected to improve the VLC system performance. In this article, we propose an optical interference alignment (OIA) approach to minimize mutual interference, where the conventional decoding-as-noise scheme is not applicable. A concrete algorithm...
