Abstract

In this paper, we have proposed a novel modulation scheme for visible light communication (VLC), that has two preprocessing blocks namely, discrete Fourier transform (DFT) block and frequency domain signal shaping block, prior to conventional optical-orthogonal frequency division multiplexing (O-OFDM) modulation. Two variants of proposed scheme namely, with and without DC have been implemented so as to make it compatible with intensity modulation and direct detection (IM/DD). The results of the proposed schemes are compared against their standard O-OFDM counterparts based on peak-to-average power ratio (PAPR) and symbol error rate (SER). Results show that the proposed scheme has significantly lower PAPR and better SER as compared to corresponding O-OFDM counterpart.
