Alleviation of LED nonlinearity impact in visible light communication using companding and predistortion.
IET Communications(2019)
摘要
In order to suppress the nonlinearity impact of light-emitting diodes (LEDs) on the performance of visible light communication (VLC), the combined method including companding and predistortion was proposed in this work. The modified companding and predistortion based on the LED characteristic analysis were used corresponding to the output current -input voltage (I-V) and light output-injected curr...
