我们证明了有限域上的嵌套陪集码的集合达到了任意离散无记忆点对点信道的容量。利用其代数结构，我们开发了一种编码技术，在一般的离散多址信道的通信与信道状态信息非因果分布在发射机。我们建立了一个代数编码框架，这个问题使用阿贝尔群码的合奏，从而得出一个新的可实现的速率区域。我们确定非添加剂和非对称的例子，建议可实现的速率区域是严格大于一个可实现的使用随机非结构化代码。
We prove that the ensemble of the nested coset codes built on finite fields achieves the capacity of arbitrary discrete memoryless point-to-point channels. Exploiting its algebraic structure, we develop a coding technique for communication over general discrete multiple access channel with channel state information distributed noncausally at the transmitters. We build an algebraic coding framework for this problem using the ensemble of Abelian group codes and, thereby, derive a new achievable rate region. We identify non-additive and non-symmetric examples for which the proposed achievable rate region is strictly larger than the one achievable using random unstructured codes.
