Abstract:

To enhance the transmission capacity of communication systems, Power Line Communication (PLC) and Visible Light Communication (VLC) can be cascaded to form a hybrid PLC-VLC system. In this paper, we propose a DC biased Optical Orthogonal Frequency Division Multiplexing (DCO-OFDM) system that utilizes the Discrete Hartley Transform (DHT) instead of the traditional Fast Fourier Transform (FFT) for a hybrid PLC-VLC system. Simulation results show that the DHT based DCO-OFDM system performs virtually identical to the FFT based DCO-OFDM system. The proposed system is simple in design, has less computational complexity and improves spectral efficiency.
