Abstract:
Embodiments may provide a way of communicating via an electromagnetic radiator, or light source, that can be amplitude modulated such as light emitting diode (LED) lighting and receivers or detectors that can determine data from light received from the amplitude modulated electromagnetic radiator. Some embodiments may provide a waveform in the form of chips at a chipping clock frequency that switch a light source between on and off states to communicate via light sources that can be amplitude modulated such as LED lighting. Some embodiments may provide a method of transmitting the waveform via modulated LED lighting. Some embodiments are intended for indoor navigation via photogrammetry (i.e., image processing) using self-identifying LED light anchors. In many embodiments, the data signal may be communicated via the light source at amplitude modulating frequencies such that the resulting flicker is not perceivable to the human eye.
