DPSK-OFDM System for Reliable Data Transmission using QRcode System in Mobile Devices
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
The work of 2-D barcodes is of great relevance for evaluate in wireless data transmission between handheld electronic devices. In a typical setup, any file on a mobile phone, for concrete illustration, can be transferred to a second mobile phone over a sequence of images on the LCD which are before captured and decoded on the camera of the second mobile phone. In this study, a new approach for data modulation in 2-D barcodes is confirmed, and its attitude is evaluated in allegory to contrasting standard methods of barcode modulation. In this new approach, orthogonal frequency-division multiplexing (OFDM) modulation is used together by all of differential phase shift keying (DPSK) over adjacent frequency domain elements. A specific desire of this study is to establish a system that is proven tolerant to camera movements, picture blur, and light leakage within adjoining pixels of an LCD.
