摘要：
When a big path difference exists between the multiple transmitter-receiver links, time dispersion is inevitable. A multipath channel model is proposed for Multiple-input multiple-output (MIMO) Visible light communications (VLC). To combat Inter-symbol interference (ISI) as well as increase the channel capacity, a combination of MIMO and Direct-current-biased Optical orthogonal frequency division multiplexing (DCO-OFDM) is studied. The performance analysis of MIMO-DCO-OFDM taking into account the limitation of the forward current of the off-the-shelf LED is derived. The accuracy of the theoretical results is verified by comparison with the Monte Carlo Bit error ratio (BER) simulation results under different DC bias and different clipping levels.
