| Popis: | This paper reports the performance of an indoor Visible Light Communication (VLC) system using a Direct Current-biased Optical Orthogonal Frequency Division Multiplexing (DCO-OFDM) scheme with a single Light Emitting Diode (LED). The DCO-OFDM is assigned to alter the bipolar signals produced by ordinary OFDM into unipolar signals. We simulate some M-ary modulations and employ Line-of-Sight (LOS) propagation model. The results show that the Quadrature Phase Shift Keying (QPSK) modulation is the most extensive one, with BER ≤ 10-3 with lower SNR. |
