METHOD AND APPARATUS FOR POWER-EFFICIENT JOINT DIMMING AND VISIBLE LIGHT COMMUNICATION |
摘要 |
A method, an apparatus, and a computer program product for communication are provided. The apparatus obtains a message for communication using visible light communication (VLC) through a light emitting diode (LED) luminary device and formats the message using a synchronization signal followed by one or more data signals. The synchronization signal and/or the one or more data signals are modulated using a Frequency Shift Keying (FSK) modulation scheme. The apparatus further receives a dimming level value associated with a brightness of light to be emitted from the LED luminary device, generates a waveform with frequencies based on the formatted message and a duty cycle for the LED luminary device based on the dimming level value, and sends the generated waveform to the LED luminary device for communication using VLC. |

1. A method of communication, comprising:
obtaining a message for communication using visible light communication (VLC) through a light emitting diode (LED) luminary device; formatting the message using a synchronization signal followed by one or more data signals, wherein the one or more data signals are modulated using a Frequency Shift Keying (FSK) modulation scheme; receiving a dimming level value associated with a brightness of light to be emitted from the LED luminary device; generating a waveform with frequencies based on the formatted message and a duty cycle for the LED luminary device based on the dimming level value; and sending the generated waveform to the LED luminary device for communication using VLC. |
