Research on LiFi Modulation Technology in Deep Mines

LiFi modulation technology is an important technology of Light Fidelity (LiFi) in optical wireless communication, which aims to ensure the bit error rate of information transmission in harsh channel environments. In deep mines, the propagation path of LiFi optical signals is interfered by the special environment of the tunnel, which reduces the performance of the overall LiFi system. Therefore, the design of LiFi modulation technology becomes extremely challenging. The current intensity modulation/direct detection (IM/DD) the relatively high bit error rate (BER) problem of the system is not satisfactory. This paper proposes an optical signal compensation mechanism to deal with the bit error rate problem, and conducts simulation analysis to prove that the mechanism has stable bit error rate performance.
