Abstract

In this paper, we proposed a latticed indoor VLC channel model and interference cancelled ZCDVLC((Zero Correlation Duration- Visible Light Communication) system using unipolar ZCD code. As a spreading sequence, unipolar ZCD code has an excellent ACF(Auto Correlation Function) and CCF(Cross Correlation Function) characteristics. It's spreading property can solve interference problem from delay components of LED(Light Emitting Diode) transmission channel and multiple user component. In order to verify interference mitigation property of proposed system, indoor communication system was simulated and BER performance was analyzed in various interference condition including AWGN (Additive White Gaussian Noise), SON(Surrounding Optical Noise), MUI(Multiple User Interference) and MRSI(Multiple Received Signal Interference).
