Experimental Characterization of RGB LED Transceiver in Low-Complexity LED-to-LED Link [PDF]

open access: yesSensors, 2020
This paper proposes a low-complexity and energy-efficient light emitting diode (LED)-to-LED communication system for Internet of Things (IoT) devices with data rates up to 200 kbps over an error-free transmission distance up to 7 cm. The system is based on off-the-shelf red-green-blue (RGB) LEDs, of which the red sub-LED is employed as photodetector in

LED Receiver Impedance and Its Effects on LED-LED Visible Light Communications [PDF]

open access: yes2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018
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 mismatch between the LED and the post trans-impedance amplifier. The optical power dependent impedance of the LED is well fitted by a modified dispersive carrier transport model
