Abstract: Techniques are disclosed for decoding light based communication (LBC) messages transmitted between a transmitter device and a receiver device. The receiver device includes a processor that executes a process to decode a received LBC message. The processor determines a moving average and removes the moving average to provide a second digital message (with the moving average removed), to account for any noises or interferences. The moving average may be determined using a length-preserving moving average. The peak location in the second digital message is identified and used as a start position for synchronization when the peak location is above the threshold. Sampling points are derived, and logical maximum and minimum values (1's and 0's) are assigned to one or more of the sampling points. The logical values are decoded to generate a decoded sequence of data representative of the received LBC message.
