The purpose of this study is to calculate the inter-carrier interference in visible light communications due to clipping in Asymmetrically Clipping Optical - Orthogonal Frequency Division Multiplexing (ACO-OFDM) signal and also to examine the distribution of this interference. Busgang's model, a technique widely used in the literature, can only provide statistical information about the interference caused by clipping. The method proposed in this paper can numerically determine the instantaneous value of the interference. Taylor series expansion is used to approximate the actual interference caused by clipping and satisfactory performance is achieved.
