Popis: | The performance of visible light communication (VLC) system may potentially be degraded by wireless optical channel distortions resulting from path loss and temporal dispersions. In order to devise techniques to combat the effects of channel distortions, an accurate channel model is needed. In this paper, we propose a new field of view (FOV) geometry-based single bounce (GBSB) model for VLC channels. Statistical properties of the proposed GBSB model are then studied, such as the channel gain, mean excess delay, root mean square (RMS) delay spread, Rician factor, and time correlation. Also, the required illuminance for the proposed scenario and the number of light emitting diodes (LEDs) per LED lamp are estimated. |
