1. A method for error correction in decoding data comprising:

  • receiving, by an apparatus, values determined from frames, the values indicative of light emanated from a light source, wherein the frames comprise a packet of data;

    processing, by the apparatus, the values to determine chips, wherein processing the values comprises selecting chips indicative of the values, wherein the chips are indicative of on and off states of the light source in the respective frames;

    processing, by the apparatus, the chips to determine a location of a start frame delimiter within the chips; and

    processing, by the apparatus, the chips, based upon the location of the start frame delimiter within the chips, to determine bits of the packet of data.
