Channel in Multiple Transmitter Visible Light Communication

Visible Light Communication (VLC), which is based on the idea of using light sources used for lighting in data transmission, expected to be among communication technologies future. However, reliable communication, it important know and predict indoor VLC channels that are known have a multipath structure. Therefore, order examine possible channel characteristics, multiple transmitter rooms with different sizes arranged study. Channel Impulse Responses Frequency were calculated receiver locations taking into account mobile users. As result study, has been shown transmitters powerful factor changes characteristics frequency selective formed related distribution location. In same room, depending location, there may completely fluctuation band some serious fading observed frequencies. This attracted attention especially as problem pending solution At end was by simulations directed illumination or detector narrow field view reduce selectivity channel.
