Ryuhei Mori, Toshiyuki Tanaka

摘要:

信道极化是一种构造对称二进制输入离散无记忆信道(B-DMC)的容量实现码的方法[1]。在原始论文中,构造复杂度是块长度的指数。本文提出了一种新的构造任意对称二进制无记忆信道(B-MC)的方法。此外,新的上限和下限的极化码的块错误概率的BEC和任意对称B-MC,分别推导。

英文摘要:

Channel polarization is a method of constructing capacity achieving codes for symmetric binary-input discrete memoryless channels (B-DMCs) [1]. In the original paper, the construction complexity is exponential in the blocklength. In this paper, a new construction method for arbitrary symmetric binary memoryless channel (B-MC) with linear complexity in the blocklength is proposed. Furthermore, new upper and lower bounds of the block error probability of polar codes are derived for the BEC and the arbitrary symmetric B-MC, respectively.
