For convenience of analysis, empirical transmitter simplification is often introduced into visible light communication (VLC) channel modeling. This simplification induced impact on channel characteristics needs to be comprehensively evaluated. This paper addresses the applicability of this simplification. Six transmitter configurations with increasing LED-spacing in a LED transmitter of fixed number...
Channel modeling is a vital issue in visible light communications (VLC) system design. Up to now, at least four channel modeling schemes are widely utilized in analysis of VLC multipath transmission characteristic, i.e. the line-of-sight (LOS), single reflection, multiple reflections and integrating-sphere (IS) modeling schemes, which contain obviously different channel components. However, the accuracy...
