8b / 10b encoding adapt the characteristic of fiber channel very well, it has been used in high - speed fiber transmission broadly. it avoids the appearance of continuous “ 1 ”, “ 0 ”, offers plenty of bit synchronization time information, enhances the stability of output light signal, reduces interference between signals and offers proper redundancy to check error through transmission
它避免了連「 1 」 、連「 0 」碼的出現，提供了豐富的位同步定時信息，減少了直流基線漂移，提高了光輸出功率的穩定性，減少了高低頻分量，改善了信號間的串擾，提供了適當的冗餘，便於檢測系統傳輸中帶來的錯誤。 -
Effective encoding technologies to obliterate redundance and retain the image quality are the focus of research. the possibility of compression is because of high self - similarity and self - transformability redundancy of images
採用有效的壓縮編碼技術刪除冗餘，以盡量少的比特數存儲圖像，並同時保證圖像的質量，已成為研究的熱點。 -
With the requirement of real - time embedded application, a series of memory management technology to improve safety and reliability for embedded system are proposed and implemented in the thesis, including memory leak detection and collection, memory redundancy allocation, memory redundancy encoding and memory protection, then the key technology of these is researched and implemented at first, a systematic survey of research in the domain of embedded real - time and memory management is given, including the concept of real - time embedded system, the research status and tendency of real - time embedded system, the characteristic of memory model and memory management in real - time embedded system

We raised a new model that we disassemble the character into several parts, which could be recognized by computer topologically based on the high - frequency wavelet coefficients vector, disregarding the traditional extraction method that used the statistical or structural feature based on the individual pixel in the 2 - dim plane of character. moreover, the concept of multi - dim cognizing feature model was put forward by encoding the character, according to its " location and run - length information. the information confusion and redundancy could be largely eliminated, as leaded to the improving of the preciseness when recognizing the character
克服以往結構、統計方法在字元特徵提取中無法剔除噪聲、偏移等冗餘信息的不足，以認知的新思路分析圖像，給出基於小波子圖的筆劃定義，給出一種注重反映字元部分最為重要的筆劃的類型、數量、遊程、位置特徵，改進了基於字元二維圖像的統計與結構特徵提取方法因變形，畸變造成信息混淆和冗餘；給出了提取多屬性字元認知特徵的方法和識別機制，實驗表明，該方法能有效的識別字元； 3 -
Firstly, the discrete multi - tone processing in an adsl central office - side interface card is detailedly introduced. the processing mainly includes timing, framing, interleaving, forward error correction, cyclic redundancy check, constellation encoding, inverse fast fourier transform processing, prefixing, d / a converting, and amplifying. secondly, a kind of interface named utopia level 2 is used as the network interface, with which many adsl devices are linked with one atm layer
本文比較詳細地闡述了數字用戶線接入模塊（ dslam ）開發方案中， adsl局端介面模塊的dmt編碼與調制過程，討論了其組網應用方式以及基於atm的網路側介面utopia2技術，分析了adsl與其它寬帶接入技術的相互聯系和優缺點，並介紹了方案中所採用的一些關鍵技術，包括在線插拔技術、系統同步啟動和故障自動重起技術以及高速數字信號完整性的保證技術等等。 -
What the part of the principle of video reduced narrates mainly is that there is plentiful temporal redundancy between adjacent frames in a video sequence for their " similarity " and there is a lot of spatial redundancy in each pixel within a frame for their " similarity ", the video is compressed by reducing spatial and temporal and statistical redundancy with the technology of dpcm and dct and huffman encoding
視頻壓縮原理部分介紹了視頻序列的相鄰幀之間的「相似」而存在大量的時間冗餘度，幀內各相鄰象素的「相似」而存在大量的空間冗餘度。通過使用dpcm 、 dct和huffman編碼去除了時間、空間及統計冗餘度，從而實現了視頻的壓縮。 -
This redundancy is useful in that it shows off each of the three most important encoding styles you are likely to find in the use of dcmi
這種冗餘性很有意義，因為它說明了dcmt應用中可能遇到的三種最重要的編碼風格：
