US Patent 9762320 Techniques for enhancing baud rate in light-based communication

Techniques are disclosed for coding light-based communication (LCom) data in a manner that allows for detection thereof, for example, via a standard low-speed (e.g., 30 frames per second) smartphone camera. In accordance with some embodiments, the disclosed techniques can be used, for example, in encoding and decoding LCom data in a manner that: (1) prevents or otherwise minimizes perceivable flicker of the light output by a transmitting LCom-enabled luminaire; and/or (2) avoids or otherwise reduces a need for additional, specialized receiver hardware at the receiver computing device including the camera. In some cases, the disclosed techniques can be used, for example, to enhance the baud rate between a transmitting LCom-enabled luminaire and a receiver device.
