Multi-path Channel Estimation in Mobile Visible Light Communication Based on Decision Feedback

In the mobile vehicle network using street lamps, in order to track the time-varying multipath VLC channel, we propose a novel outdoor mobile visible light communication channel estimation method based on decision feedback. With different system parameters, simulations and analysis are carried out. Results show that compared with the conventional scheme, the proposed method can reduce the bit error rate below 10
^-4
, thus effectively improve system performance for the mobile VLC channel.
