Özet
Filtered-OFDM scheme recently considers a promising element for Visible Light Communication (VLC) systems. Converting the F-OFDM bipolar signal to a nonnegative signal and being compatible with the Intensity Modulation and Direct Detection (IM/DD) is a crucial issue for researchers. To achieve a unipolar signal, many techniques have been proposed. In this paper, a Direct Current-bias (DC-bias) technique is employed to acquire a signal unipolarity and evaluate the efficiency of the F-OFDM system. The simulation findings offer that when the DC bias increased, the peak-to-average-power ratio (PAPR) increased even when using different modulation orders. In contrast, comparing different modulation orders, F-OFDM shows better bit error rate (BER) performance, especially in low-order modulation schemes.
