  • For the anticounterfeiting of printings ( such as certificate ) , the existent many ways ( such as rainbow holograms ) are not available as the need for special use : anti - distortion and anti - copy . basing in the double - random - phase transform , this article puts forward a new way that two - dimensional bar code is used as anticounterfeiting label with anti - printing ? scanning and anti - damage properties . the major job are : ( 1 ) . basing in the ascii codes , numerals and alphabets are encoded and subsequently transformed into two - value bar code matrix figure . later , using amplitude - based double - random - phase transform , the enciphered gray scale figure is formed . by computer simulation ( 4f system ) and printing as well as scanning ( 20 times ) , we get the result that the gray scale figure with little miscoding rate ( 0 . 0026 ) by “ matrix expanding way ”
    本文主要开展了以下三项研究工作: ( 1 ) .用自定义编码方案,将数字和字母( ascii码)转换成二值条码图;对该图形进行振幅型双随机相位加密变换,得到原信息的加密灰度图;通过4f光学系统计算机模拟和打印-扫描实验,证明本文提出的“矩阵扩展法”灰度图具有较小的误码率,对于20次打印-扫描实验,误码率不大于0 . 0026 。
  • This thesis introduces the concept of qosmecs and proposes a new method to construct the square - matrix embeddable space - time block codes matrices based on the works of tarokh , alamouti and jafakhani etc . comparing to the previous works , the construction formulas presented here are much simple with the same performance of the matrices constructed
    本文基于tarokh 、 alamouti和jafakhani等人的研究成果,引入了准正交方阵嵌入码的概念,提出了一种新颖的方阵嵌入空时分组码的设计方法。在生成同样性能码矩阵的情况下,本文提出的构造公式与已有设计方法相比要简单得多。
