Research Initiation: Coding Algorithms for Correcting CycleSlips and Errors

最近的研究表明，错误的主要原因是 某些数字数据网络是由于发生周跳 在时钟恢复期间，而不是在 检测器 常规码不能容忍周跳， 并且可能使问题变得更糟。 本项目的目标 是开发新的和有效的编码算法， 正确的滑。 此外，所研究的编码算法将 具有有限的纠错能力，因此， 偶尔的错误可以被纠正，因此， 算法对错误不敏感。 研究有两个不同的方向。 以前的研究 在该地区已经导致了一些相当有效的发展 可以容忍周跳的代码在边界之间 代码，但没有别的地方。 这项研究探讨了如何 扩展或修改这些代码，使它们能够正确循环 出现在码字中任何地方的滑动。 另一个方向， 本研究主要是研究新的编码方法， 周跳，包括信源编码和卷积码 结构。*/

Recent research has shown that the principal cause of errors on some digital data networks is due to cycle slips that occur during clock recovery, instead of erroneous decisions made at the detector. Conventional codes are unable to tolerate cycle slips, and can make the problem worse. The objectives of this project are to develop new and efficient coding algorithms that can correct slips. In addition, the coding algorithms studied will have a limited error correction capability, so that the occasional error can be corrected and so that the resulting algorithms are not sensitive to errors. The research has two different directions. Previous research in the area has led to the development of some fairly efficient codes that can tolerate cycle slips at the boundary between codewords, but nowhere else. The research examines ways to extend or modify these codes so that they can correct cycle slips that occur anywhere in the codeword. Another direction for the research is the study of novel coding methods for correcting cycle slips, including source coding and convolutional code structures.***//
