本文的目的是使用晶格和代数代码的组合研究任何信噪比的K-用户高斯干扰通道（G-IFC）的可实现速率。晶格代码首先用于将G-IFC转换为离散输入 - 输出无噪声通道，然后开发代数代码以在此新字母上实现良好的速率。在这种情况下，引入了一个称为效率的数量，反映了代数编码策略的有效性。本文首先解决了寻找高效代数代码的问题。然后使用这些代码与构造A晶格的组合来实现原始G-IFC的非平凡率。
The aim of this paper is to study the achievable rates for a K-user Gaussian interference channel (G-IFC) for any signal-to-noise ratio using a combination of lattice and algebraic codes. Lattice codes are first used to transform the G-IFC into a discrete input--output noiseless channel, and subsequently algebraic codes are developed to achieve good rates over this new alphabet. In this context, a quantity called efficiency is introduced which reflects the effectiveness of the algebraic coding strategy. This paper first addresses the problem of finding high-efficiency algebraic codes. A combination of these codes with Construction-A lattices is then used to achieve nontrivial rates for the original G-IFC.
