修正编码
Examples
- In this paper , we mainly describe the digital watermarking technologies of information security . we firstly introduced the research backgrounds , basic principles , application areas and recent development of the digital watermarking technology . then we adopted some new technologies such as chaos , svd ( singular value decomposition ) , anns ( artificial neural networks ) , ecc ( error correction code ) , into the digital watermarking and proposed several different kinds of watermarking schemes : watermarking with chaos control ; watermarking in svd domain ; robustness enhancement with anns and ecc
本文主要探讨网络信息安全中的数字图像水印技术，介绍了数字水印的研究背景、基本原理、应用领域以及当前国内外的发展状况，文中结合混沌技术、 svd变换、神经网络和差错控制编码等技术提出了多种不同类型水印算法方案，它们分别是：混沌技术在数字水印技术中的应用； svd变换域中的数字水印方案；基于神经网络和纠错编码应用的稳健性增强方案。 - If no errors occur in it , the parity check part itself can retrieve the information by invertible process . if errors occur , the parity check part will be combined with the previously received information part to build an error - correction code , and try to recover the information . this kind of harq can match channel states very well
该harq将信息码字和校验码字分开传送，信道状态较好时只传送信息码字；信道变差时才要传送校验码字，校验码字可单独或与信息码字一起将信息恢复出来，因此这种结构对信道有较好的适应性。 - Mechanism and difficulty of current real - time transport technology are analyzed in this article , technologies such as multicast , real - time transport , resource reservation and error correction code technologies are studied in this dissertation . a method of improving the quality of real - time transport of multimedia data on network on where packet loss rate and packet error rate are high is provided
本文分析了现有网络数据实时传输的机理及面临的困难，研究了多播、实时传输、资源预留以及纠错编码等技术在实时传输中的应用，给出了在低带宽、包错误率和丢包率较高的网络中提高多媒体数据实时传输质量的方法，提出了带动态纠错编码的实时传输技术。 - Simulations on the key technique of spread spectrum communications are studied here , according to the characteristic of lduwarc system , issues concerning pseudo - noise codes , spread spectrum method , correlation receiving and synchronization . we also design an error correction code for the system
论文还对扩频通信的关键技术进行了仿真研究，针对远程声遥控系统的特点，讨论了扩频码、扩频方式、相关接收和同步问题，同时讨论了适合远程声遥控系统的纠错编码技术。
