Nonlinear Noise Analysis About White LED in Visible Light Communication
An algorithm of nonlinearity noise led by LED nonlinearity was proposed. The signal-to-noise ratio and bit error rate of visible light communications system with OOK modulation could be obtained through the algorithm. The curve about the relation between LED bias point and bit error rate were plotted with Matlab simulation. The results were proved by visible light communication system image transmission experiment. The curve has great significance on the choice of proper LED model and bias point about VLC system experiment.
