极化码的低复杂度删截与缩短

Low-Complexity Puncturing and Shortening of Polar Codes

Valerio Bioglio, Frederic Gabry, Ingmar Land

摘要:

在这项工作中,我们从统一的角度解决了缩短和打孔极化码的低复杂度构造。虽然在文献中尝试了几种独立的打孔和缩短设计,但我们的目标是一种独特的、低复杂度的结构,包括这两种技术,以实现任何代码长度和速率。我们观察到,与最先进的解决方案相比,我们的解决方案显著降低了构造复杂性,同时提供了与针对特定长度和速率高度优化的构造相当的块出错率性能。这使得所构造的极化码非常适合于需要具有不同长度和速率的大量极化码的未来通信系统中的实际应用。

英文摘要:

In this work, we address the low-complexity construction of shortened and punctured polar codes from a unified view. While several independent puncturing and shortening designs were attempted in the literature, our goal is a unique, low-complexity construction encompassing both techniques in order to achieve any code length and rate. We observe that our solution significantly reduces the construction complexity as compared to state-of-the-art solutions while providing a block error rate performance comparable to constructions that are highly optimized for specific lengths and rates. This makes the constructed polar codes highly suitable for practical application in future communication systems requiring a large set of polar codes with different lengths and rates.
