MDP和完全MDP卷积码的必要域长度和概率

Necessary Field Size and Probability for MDP and Complete MDP Convolutional Codes

Julia Lieb

摘要:

已经表明,当在擦除信道上传输时,最大距离轮廓(MDP)卷积码对于特定长度的窗口具有最佳恢复率。此外,完全MDP卷积码的子类具有减少解码期间的等待时间的能力。在本文中,我们推导出上界的必要字段的大小存在的MDP和完整的MDP卷积码,并表明,这些边界改善了现有的。此外,我们推导出一个随机码是MDP各自的完整MDP的概率的下界。

英文摘要:

It has been shown that maximum distance profile (MDP) convolutional codes have optimal recovery rate for windows of a certain length, when transmitting over an erasure channel. In addition, the subclass of complete MDP convolutional codes has the ability to reduce the waiting time during decoding. In this paper, we derive upper bounds on the necessary field size for the existence of MDP and complete MDP convolutional codes and show that these bounds improve the already existing ones. Moreover, we derive lower bounds for the probability that a random code is MDP respective complete MDP.
