Abstract:

There are numerous possible applications for a high data density barcode that can be easily photographed and decoded by mobile phones, but no such symbology presently exists. As a outcome, a new barcode was intended to exploit the low-pass characteristic of a camera phone channel and is offered as a means of enabling wireless optical communication with mobile phones.In this study, a new method for data modulation in 2-D barcodes is presented, and its performance is evaluated in contrast to other standard methods of barcode modulation. In this new method, orthogonal frequency-division multiplexing (OFDM) modulation is used together with differential phase shift keying (DPSK) over next to frequency domain elements.

Keywords:

Barcode, data transfer, differential phase shift keying, orthogonal frequency-division multiplexing (OFDM) modulation.
