论文摘要
在这封信中，我们提出了一种累进率填充方法，作为研究多层极地编码调制的敏捷构造的框架。我们表明，每个组件极性代码中的位索引可以遵循固定的预算排名序列，例如5G标准中的极性序列，而它们的分配速率（即，每个组件极性代码的信息位的数量）可以通过利用目标总和率近似值和适当的费率填充方法来快速计算。特别是，我们根据能力和考虑有限的块长度效应的能力和速率制定了两种填充策略。拟议的构造方法可以独立于实际的频道条件执行$ {o \ left（m \ right）} $（$ m $表示调制顺序）的复杂性，并且对5G标准中的各种调制和编码方案进行了鲁棒性，这是实用系统的期望功能。
In this letter, we propose a progressive rate-filling method as a framework to study agile construction of multilevel polar-coded modulation. We show that the bit indices within each component polar code can follow a fixed, precomputed ranking sequence, e.g., the Polar sequence in the 5G standard, while their allocated rates (i.e., the number of information bits of each component polar code) can be fast computed by exploiting the target sum-rate approximation and proper rate-filling methods. In particular, we develop two rate-filling strategies based on the capacity and the rate considering the finite block-length effect. The proposed construction methods can be performed independently of the actual channel condition with ${O\left(m\right)}$ ($m$ denotes the modulation order) complexity and robust to diverse modulation and coding schemes in the 5G standard, which is a desired feature for practical systems.
