Abstract

Visible Light Communication (VLC) using LED Light Fidelity (Li-Fi) has been proposed as a good substitute for the RF communication, and it uses visible-range electromagnetic spectrum to transmit data. A low complexity text transmission system for short-range LIFI communication is proposed in this paper using low- cost hardware. The proposed one consists of an Arduino-based source and a detector as transmitter and receiver, respectively, where linguistic symbols are used to be encoded in terms of light pulse intensity modulations from the light- emitting diode (LED) and here demodulated in the end back to their respective forms using a Light-dependent Resistor (LDR). The simplistic pulse-duration modulation is used to make symbol detections robust at a minimal amount of computation cost. Details of the entire system, which consists of system architecture, hardware design, and data processing flow, are presented. Experimental results show that it is possible for the accurate transmission of text under indoor lighting at close distances. Due to its low complexity, cost, and immunity to electromagnetic disturbances, the proposed macro-diversity is applicable not only for educational platforms but also for indoor communications where RF communication is limited. The proposed design serves as a workable basis for the future improvements to be made toward higher data rates and more immune V-LC systems.
