We propose the 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 propose two rate-filling methods based on the capacity and the rate considering the finite blocklength effect. The proposed construction methods can be performed independently of the actual channel condition with ${O(m)}$ (
${m}$ denotes the modulation order) complexity and robust to diverse modulation and coding schemes (MCSs) in the 5G standard, which is a desired feature for practical systems.

渐进速率填充:多级极性编码调制的敏捷构建框架
我们提出了渐进式速率填充方法作为研究多级极性编码调制的敏捷构造的框架。我们表明,每个分量极性码内的比特索引可以遵循固定的,预先计算的排名序列(例如5G标准中的Polar序列),而它们的分配速率(即每个分量极性码的信息比特数)可以是通过利用目标总速率近似值和适当的速率填充方法来快速计算。特别是,考虑到有限的块长效应,我们提出了两种基于容量和速率的速率填充方法。所提出的构造方法可以独立于实际的信道条件执行, $ {O(m)} $ (
$ {m} $ 表示调制阶数)的复杂性,并且对5G标准中的各种调制和编码方案(MCS)具有鲁棒性,这是实际系统所需的功能。
