Analysis of maximum security rate based on MIMO indoor visible light communication system
Visible light communication(VLC) physical layer security research plays an important role in the commercialization and popularization of VLC. Based on a multi-input multiple output(MIMO) indoor VLC system, the lower limit expressions of the se-curity capacity in the case of eavesdroppers colluding and non-colluding are derived and compared. Then, an optimal beam forming scheme is proposed to maximize the security rate in the case of non-colluding. Finally, numerical simulation is carried out. The simulation results show that the confidentiality capacity in the case of non-collusion is better than that in the case of collusion, and the number of eavesdroppers only has an effect on the confidentiality capacity in the case of collusion.
