二元线性码盲检测的计算复杂性

On the Computational Complexity of Blind Detection of Binary Linear Codes

Alexios Balatsoukas-Stimming, Aris Filos-Ratsikas

摘要:

在这项工作中,我们研究了最小距离码检测问题的计算复杂性。在这个问题中,我们给出了一组噪声码字观测值,我们希望在给定维度$k$的线性码$\mathcal{C}$的集合中找到一个码,对于该码,观测值和码之间的距离之和最小化。我们证明,对于实际相关的情况下,当集$\mathcal{C}$只包含一个固定数量的候选线性代码,检测问题是NP-难的,我们确定了一些有趣的开放问题有关的代码检测问题。

英文摘要:

In this work, we study the computational complexity of the Minimum Distance Code Detection problem. In this problem, we are given a set of noisy codeword observations and we wish to find a code in a set of linear codes $\mathcal{C}$ of a given dimension $k$, for which the sum of distances between the observations and the code is minimized. We prove that, for the practically relevant case when the set $\mathcal{C}$ only contains a fixed number of candidate linear codes, the detection problem is NP-hard and we identify a number of interesting open questions related to the code detection problem.
