Visible Light Communication (VLC) System with Reduced Peak to Average Power Ratio (PAPR) for High Speed Data Transmission
S. Yogeeswaran and G.P. Ramesh
 
Abstract: In recent times, Visible Light Communication (VLC) is used for high speed transmission using optical wireless communication. VLC contains high power LEDs for high speed data communication. This technique has throughput limitations because the LED bandwidth is limited. To improve the data rate and spectral efficiency of the VLC by using the Orthogonal Frequency Division Multiplexing (OFDM). To propose a novel OFDM based VLC technique improving the efficiency compared to the conventional optical based OFDM system. The existing technique obtained the real and positive values from IFFT operation. The values are taken from the Hermitian symmetry and signal clipping approach, it increased the Peak-to-Average Power Ratio (PAPR). The proposed technique reduces the PAPR without using the Hermitian symmetry. It also increases the efficiency of the system.
