    Nonlinear Visible Light Communications Broadcast Channel Precoding: A New Solution for In-flight Systems by Dario Tagliaferri, Andrea Matera, Carlo Capsoni, Umberto Spagnolini

    Published 2018-01-01
    “…Since nominal lighting is constrained by LEDs saturation, here we adapt the Tomlinson–Harashima precoding algorithm to the on-board VLC scenario and demonstrate its definite improvement on channel capacity with respect to the unprecoded case and also to the zero-forcing precoding one. The optimum directivity of the sources trades over performance and robustness against source-receiver misalignments (i.e., the passengers’ mobility) by validating MISO channels for a number of receivers’ positions around the best alignment one with a ray tracer specifically designed.…”
