COMMUNICATION IN VISIBLE LIGHT IMAGING-MIMO SYSTEM USING µLED AND BUILT-IN RECEIVER
Abstract. Multiple input multiple output (MIMO) transmission can be used to increase the capacity of visible light communication (VLC) systems. This approach is well compatible with the use of micro light emitting diode (µLED) arrays. In this paper, we demonstrate a VLC-MIMO imaging system using a 2D array of individually addressable microLEDs and an integrated […]
STUDY OF COMMUNICATION IN VISIBLE LIGHT USING PIM AND PPM FORMATS FOR SIMULTANEOUS DATA TRANSMISSION
Abstract. A visible light communication system with simultaneous brightness control and data transmission is experimentally demonstrated in this paper. A pulse-width modulation (PWM) scheme is adopted for brightness control of the light-emitting diode and pulse- position modulation (PPM) superimposed on top of PWM is used for data communications. We show that independent control of light […]
