Abstract: Light-based communication (LCom) techniques are disclosed for decoding LCom signals using a sub-raster line sampling process. In accordance with an embodiment, a system is provided that is configured to sub-sample each raster line to capture data at a much faster sampling rate, which in turn allows for longer LCom messages and faster response time.

However, by sub-sampling the raster lines as provided herein, the sampling rate can be a combination of horizontal and vertical pixels which represents a substantial improvement over standard raster line based rolling shutter modes.

The receiver can selectively sample the signal based on synchronization information to determine whether the received signal contains the emitted pulse pattern. Through-beam sensor embodiments can generate the synchronization information internally based on an analysis of the analog signal corresponding to the modulated signal.
