Enhanced Intensity-Weighted Receiver Design for SiPM-Array VLC: Shot-Noise-Aware Channel Selection and Experimental Validation

Visible Light Communication (VLC) benefit from array reception, which improve the receiver sensitivity, extend the transmission distance, and enhance the link reliability in mobile applications. In this paper, we design a VLC receiver architecture centered on a Silicon Photomultiplier (SiPM) array. To address the joint time-varying effect produced by transmitter and array position displacement, a two-step shot-noise-aware signal-processing framework at the receiver-side is developed. Then, a thr
