| description | In this article, a DC-biased optical–orthogonal frequency-division multiplexing visible light communication systems based on multi-point light-emitting diodes-array sources in the special-type vehicle is investigated. The novel lighting layout based on optical power evenly distribution principle is proposed to meet the desired lighting and communication requirement. Meanwhile, in order to resist the inter-symbol interference caused by multipath dispersion, DC-biased optical–orthogonal frequency-division multiplexing modulation strategy is suggested. The performance parameters of signal-to-noise ratio, the root-mean-square delay spread, and maximum transmission rate have been analyzed and calculated theoretically based on direct and multipath reflected channel models of visible light communication. The validity of the visible light communication system is demonstrated by simulation experiments results as follows: the received optical power range of −0.73 to 0.56 dBm in vehicle for approximately 2 m × 2 m × 1.5 m cube space, uniform illumination rate is 80.5%, average signal-to-noise ratio is 20.92 dB. Moreover, the maximum data rate can be improved from 107.8 to 477.4 Mb/s with the bit error rate at approximately 10 −5 , which meet the illumination and data transmission rate requirement for the special-type vehicle. |
