摘要

本文建立了长度兼容(LC)穿孔/缩短极性码与复合极性码之间的联系。将LC码作为在两个不同信道上传输的复合码，我们提出了四个信道编码的位映射规则，这些规则推广了一些已知的LC码构造方法。通过检查Bhattacharyya边界是否最小，可以预测应用不同映射规则构造的穿孔码和缩短码的性能。

Design of Length-Compatible Polar Codes: A Compound Polar Code's Perspective

In this paper, we establish a connection between length-compatible (LC) punctured/shortened polar codes and compound polar codes. Regarding an LC code as a compound code to be transmitted over two different channels, we propose four channel-coded bit mapping rules which generalize some known LC code constructing methods. Performance of the punctured and shortened codes constructed by applying different mapping rules can thus be predicted checking if the Bhattacharyya bound is minimized.
