Research on blind separation for the LED

Optical Signal The paper research the problem for multi-path effect arising from the inter-symbol interference on LED visible light communication Put forward a blind source separation method and use it to process the mixedsignal in the receiver of visible light communication. An algorithm based on the forward filter for the convolutive mixtured source signals is proposed and use it to separate double convolutive mixtured source signal,reached the purposes of suppressing inter-symbol interference.
