本文介绍了纠错码中几个重要问题,特别是与其实用密切相关的几个重要方面如:与分组码译码密切相关的码的最小距离、重量分布、复盖半径、球半径、快速译码与软判决译码等;与通信系统设计有关的调制与纠错码的结合;与系统安全性有关的加密与纠错相结合等方面的发展背景与过程,及最近进展。讨论了存在的问题及发展方向。
In this paper, we introduce several important problems in ECC, especially several important aspects that are closely related to its practicality, such as the minimum distance of code, weight distribution, radius of coverage, radius of sphere, fast translation Code and soft decision decoding, etc .; the combination of modulation and error correction codes related to communication system design; the background and process of the combination of encryption and error correction related to system security and the recent progress. Discussed the existing problems and development direction.
