论文摘要
在本文中，我们提出\ textit {有选择性预编码的polar（spp）代码}，该代码}建立在Arikan的能力上实现极性代码的顶部。我们为SPP代码提供编码和解码方案。仿真结果表明，对于目标框架擦除率（FER）的$ \ mathbf {10^{ - 5}} $，A（128，64）SPP代码在此块上方的信息理论限制仅为0.23 dB。此外，还表明，与其他当代极性代码变体相比，此类代码具有更好的距离属性。
In this paper, we propose \textit{selectively precoded polar (SPP) code}, built on top of Arikan's capacity achieving polar codes. We provide the encoding and decoding scheme for SPP code. Simulation results show that for a target frame erasure rate (FER) of $\mathbf{10^{-5}}$, a (128, 64) SPP code is just 0.23 dB away from the information theoretic limit at this blocklength. Further, it is also shown that such codes possess better distance properties compared to other contemporary polar code variants.
