LED receiver impedance and its effects on LED-LED visible light communications
Shangbin Li, Boyang Huang, Zhengyuan Xu
This paper experimentally demonstrates that the AC impedance spectrum of the LED as a photodetector heavily depends on the received optical power, which may cause the impedance mis…
