An Advanced Approach for Barcode Modulation Using High Capacity 2D Barcode Technique

Between handheld electronic gadgets in wireless data transmission for use the concept of HC2D barcode is of great relevance. In a typical setup, through  a  image series on the LCD there can  be  transferred  any file on a phone to  a  second  cell  phone through the  camera  of  the  second  cell  phone which are then captured and decoded.  In  this  study,  in HC2D barcodes a  new  approach for data modulation is proposed, and to  other  standard methods of barcode modulation its  performance  is  evaluated  in  comparison. In the new approach, within neighboring pixels of a LCD over adjacent blur, and light leakage, there is used the orthogonal frequency-division multiplexing (OFDM) modulation together with differential phase shift keying (DPSK). Keywords— HC2D barcode, differential phase shift keying, data transfer, orthogonal frequency-division multiplexing (OFDM) modulation.
