DPSK - OFDM modulation scheme is implemented in the proposed work to handle the complexity issue in flexible manner for hassle - free data transmission in mobile devices. Barcode scheme has ability to convert the readable form of information into un - understandable form to provide complexity free transmission. Barcode print ed on paper has interference free appearance which does not have any leakages while digital barcodes has observed while pixels are leaked into their corresponding black pixels which is called as intersymbol interference. The proposed barcode based DPSK - OFD M system are designed to reduce the issues frequently occurs in handheld device transmission with low complexity and high performance as resultant outcome. The contribution work continued to proposed work is implemented on DWT - OFDM which results in low com plexity than the proposed work with high performance as outcome.
