摘要: 极化码是一种理论上能够达到任意对称二进制离散无记忆信道(B-DMC)信道容量的新型信道编码技术。本研究介绍了信道极化的基本原理,并针对一般情况,以偏序法为例,详细阐述了具有4阶核矩阵的极化码构造原理,并采用串行相消译码器研究其译码过程。最后,对极化码潜在的研究方向和可能遇到的困难点进行了探讨。

Abstract: Polar code is a new channel coding technology that can theoretically achieve the channel capacity of any symmetrical binary discrete memoryless channel (B-DMC). This paper introduces the basic principles of channel polarization, and for general situations, taking the partial order as an example. This paper elaborates the construction principle of the polarization code with a fourth-order kernel matrix in detail, and use a successive cancellation decoder to study its decoding process. Finally. This paper summarizes the research directions and possible difficulties of polarization codes.
Key words: polar codes; likelihood ratio; successive cancellation decoder; partial order
