For transmitting the data of information in between the wireless devices as like handheld electronic devices such mobile phones that time two-dimensional barcode i.e. 2-D barcodes used in with great importance. When the user want to transfer a series of images from one cell phone to other cell phone that time it can be transferred from one cell phone to other cell phone through the LCD which are then captured and decoded by using the other cell phone camera. The data modulation in

The Orthogonal Frequency-Division Multiplexing i.e. OFDM and Differential Phase Shift keying i.e. DPSK is used together for a contiguous frequency domain elements. To implementing such type of system the movements of camera when the user capturing the image, image blur and leakage of light within neighboring pixel of an LCD, so we worked on this issue and trying how to overcome on it. Keywords-Study of Barcode, Data Transmission in between the devices, OFDM, DPSK Modulation techniques.
