Research Initiation: Coding Algorithms for Correcting CycleSlips and Errors

最近的研究表明，某些数字数据网络上出现错误的主要原因是时钟恢复期间发生的周跳，而不是检测器做出的错误决策。 传统代码无法容忍周跳，并且会使问题变得更糟。 该项目的目标是开发能够纠正错误的新的高效编码算法。 另外，所研究的编码算法将具有有限的纠错能力，从而可以纠正偶然的错误，并且使得所得算法对错误不敏感。 该研究有两个不同的方向。 先前该领域的研究已经导致开发了一些相当有效的代码，这些代码可以容忍码字之间边界处的环跳，但不能容忍其他地方。 该研究探讨了扩展或修改这些代码的方法，以便它们可以纠正代码字中任何地方发生的循环跳变。 研究的另一个方向是研究用于纠正周跳的新颖编码方法，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.***//
