一种实用的极化码

A Practical Approach to Polar Codes

Ali Eslami, Hossein Pishro-Nik

摘要:

在本文中,我们从实用的角度研究极化码。特别地,我们研究了级联极化码和速率兼容极化码。首先,我们提出了一种级联方案,包括极化码和低密度奇偶校验(LDPC)码。我们将表明,我们提出的方案优于传统的级联方案形成的LDPC和里德所罗门(RS)码。然后,我们研究了两种速率兼容的编码方案,使用极化码。我们将看到,极化码可以被设计为在一组物理降级信道上实现速率兼容的通用容量码。我们还研究了打孔对极化码的影响,以设计速率兼容码。

英文摘要:

In this paper, we study polar codes from a practical point of view. In particular, we study concatenated polar codes and rate-compatible polar codes. First, we propose a concatenation scheme including polar codes and Low-Density Parity-Check (LDPC) codes. We will show that our proposed scheme outperforms conventional concatenation schemes formed by LDPC and Reed-Solomon (RS) codes. We then study two rate-compatible coding schemes using polar codes. We will see that polar codes can be designed as universally capacity achieving rate-compatible codes over a set of physically degraded channels. We also study the effect of puncturing on polar codes to design rate-compatible codes.
