由Arikan提出的信道极化方法使我们能够构建有效的容量实现信道码。在原来的工作中，考虑了二进制输入离散的无记忆通道。Şaşoğlu、Telatar和Arikan考虑了q-ary通道极化的一种特殊情况。在本文中，我们考虑了q元通道上更一般的通道极化。我们进一步展示了使用Reed-Solomon码的显式结构，在其上诱导渐近快速通道极化。
A method of channel polarization, proposed by Arikan, allows us to construct efficient capacity-achieving channel codes. In the original work, binary input discrete memoryless channels are considered. A special case of q-ary channel polarization is considered by Şaşoğlu, Telatar, and Arikan. In this paper, we consider more general channel polarization on q-ary channels. We further show explicit constructions using Reed-Solomon codes, on which asymptotically fast channel polarization is induced.
