Visible light communication (VLC) system for small range transmission uses visible spectrum which provides illumination simultaneously. Designing cost of light emitting diodes was reduced in order to make this communication possible. A modulation technique which can effectively employ the bandwidth is orthogonal frequency division multiplexing (OFDM) technique. This technique has a unique form of subcarrier modulation scheme because in this all the subcarrier frequencies are orthogonal in nature. Orthogonal Frequency Division Multiplexing scheme are able to attain high throughput in the restricted bandwidth requirement. On the other hand, the major demerit of OFDM has a high peak-to-average-power- ratio (PAPR) which requires a high dynamic variety. High PAPR also causes nonlinear distortion which mostly affects the OFDM scheme in VLC system.
