Visible Light Communication with Increased Signal-to-Noise Ratio

摘要

A method of increasing modulation of a visible light signal. The method can include receiving a signal that corresponds to the visible light signal, where the visible light signal has a magnitude. The method can also include adjusting, by a controller and based on the signal, a dimmer level of a dimmer by an amount, where the amount is proportional to the magnitude of the visible light signal, and where the dimmer level adjusts an output of a driver circuit. The visible light signal and the output of the driver circuit can be combined into a power signal and sent to one or more light sources. The one or more light sources can use the power signal to generate a light output that includes a visible light communication signal that is received by a receiver.

1. A method of increasing modulation of a visible light signal, the method comprising:
receiving a signal that corresponds to the visible light signal, wherein the visible light signal has a magnitude; and adjusting, by a controller and based on the signal, an input signal by an amount, wherein the amount is proportional to the magnitude of the visible light signal; wherein input signal comprises the visible light signal and a power signal from a driver circuit and is received by one or more light sources, wherein the one or more light sources use the input signal to generate a light output that comprises a visible light communication signal that is received by a receiver.
