摘要

手持电子小工具之间在无线数据传输中使用的HC2D条形码的概念是非常相关的。在典型的设置中,通过LCD上的图像序列,可以将手机上的任何文件通过第二部手机的摄像头传输到第二部手机,然后捕获并解码。本研究在HC2D条码中提出了一种新的数据调制方法,并与其他标准的条码调制方法进行了比较。该方法采用正交频分复用(OFDM)调制与差分相移键控(DPSK)相结合的方法,在LCD的相邻像素内克服相邻模糊和漏光。关键词:HC2D条码,差分相移键控,数据传输,正交频分复用(OFDM)调制。

An Advanced Approach for Barcode Modulation Using High Capacity 2D Barcode Technique
Between handheld electronic gadgets in wireless data transmission for use the concept of HC2D barcode is of great relevance. In a typical setup, through  a  image series on the LCD there can  be  transferred  any file on a phone to  a  second  cell  phone through the  camera  of  the  second  cell  phone which are then captured and decoded.  In  this  study,  in HC2D barcodes a  new  approach for data modulation is proposed, and to  other  standard methods of barcode modulation its  performance  is  evaluated  in  comparison. In the new approach, within neighboring pixels of a LCD over adjacent blur, and light leakage, there is used the orthogonal frequency-division multiplexing (OFDM) modulation together with differential phase shift keying (DPSK). Keywords— HC2D barcode, differential phase shift keying, data transfer, orthogonal frequency-division multiplexing (OFDM) modulation.
