摘要

提出了一种有效的极化码穿刺技术。代码是基于一个属性来构造的,在这个属性中,代码的生成矩阵可以用短代码的生成矩阵来表示。考虑到这种结构,可以得出结论,对于一个代码所考虑的穿孔位也可以作为更长的代码的穿孔位。这导致实现一个穿刺算法,可用于短或长长度的代码。通过模拟证实,新的穿刺技术优于先前提出的技术。这对于不同的代码速率是很明显的。

An efficient puncturing method for the short and long length polar codes
An efficient puncturing technique for polar codes is presented in this paper. Codes are constructed based on a property, in which the generator matrix of the code can be represented based on the generator matrix of shorter codes. Considering this structure, it is concluded that punctured bits considered for a code can also be used as the punctured bits of the longer code. This leads to implement a puncturing algorithm that can be used for the short or long length codes. Conducted simulations confirm that the new puncturing technique outperforms the previously proposed ones. This is evident for different code rates.
