混合核极化码

Polar Codes with Mixed-Kernels

Noam Presman, Ofer Shapira, Simon Litsyn

摘要:

介绍了一种称为混合核的极化编码方案的推广。这种推广利用了不同大小的字母表上的几个同质内核。对该方案的渐近分析表明,其偏振特性与组成核的偏振特性密切相关。有限长度实例的仿真结果表明,该方案在纠错性能和复杂度方面都优于已知的极化编码结构。

英文摘要:

A generalization of the polar coding scheme called mixed-kernels is introduced. This generalization exploits several homogeneous kernels over alphabets of different sizes. An asymptotic analysis of the proposed scheme shows that its polarization properties are strongly related to the ones of the constituent kernels. Simulation of finite length instances of the scheme indicate their advantages both in error correction performance and complexity compared to the known polar coding structures.
