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 ”
本文主要開(kāi)展了以下三項(xiàng)研究工作: ( 1 ) .用自定義編碼方案,將數(shù)字和字母( ascii碼)轉(zhuǎn)換成二值條碼圖;對(duì)該圖形進(jìn)行振幅型雙隨機(jī)相位加密變換,得到原信息的加密灰度圖;通過(guò)4f光學(xué)系統(tǒng)計(jì)算機(jī)模擬和打印-掃描實(shí)驗(yàn),證明本文提出的“矩陣擴(kuò)展法”灰度圖具有較小的誤碼率,對(duì)于20次打印-掃描實(shí)驗(yàn),誤碼率不大于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，引入了準(zhǔn)正交方陣嵌入碼的概念，提出了一種新穎的方陣嵌入空時(shí)分組碼的設(shè)計(jì)方法。在生成同樣性能碼矩陣的情況下，本文提出的構(gòu)造公式與已有設(shè)計(jì)方法相比要簡(jiǎn)單得多。
