DWT-IDWT Based Barcode Modulation Method for Verification

There are several wireless data transmission techniques in which barcodes are of great relevance. In this new approach 2D barcode is forward and its enactment may be contrasted with different standard systems. For analysis purpose, the low-pass trademark of a camera phone channel and has been exhibited for encouraging wireless optical communication with versatile handheld mobile telephones. In this method, orthogonal frequency-division multiplexing (OFDM) modulation is utilized together with differential phase shift (DPSK) through contiguous frequency dominion components. Proposed method aims furthermore to create an arrangement that is accepting camera activities in different variations, image fuzziness along with light spillage inside neighboring pixels of an LCD.
