Abstract

In the optical wireless communication system, a reliable transmission channel can be achieved in the power restricted scene by using a single-photon avalanche diode (SPAD) receiver. However, the performance of SPAD is limited by dead time. This results in count loss and inter-slot interference (ISI), which degrades the communication performance. In this paper, a 4-channel time-gated scheme was proposed. In the scheme, time-gated SPAD receivers successively turned on by external gating signals to reduce the effective dead time of the receiving system and improve the signal-to-noise ratio. In addition, the 4 time-coordinated receivers scheme has better background light tolerance and better performance in intensive signal power condition than the 4 free-running SPADs receivers scheme.
