摘要

我们考虑在有限域Fq\mathbb{F}_{q}上由2×22\times 2[10α1]\begin{bmatrix} 1 & 0 \\ \alpha & 1 \end{bmatrix}构造的极化码,其中q=psq=p^s为素数pp的幂,且α\alpha满足Fp(α)=Fq\mathbb{F}_{p}(\alpha) = \mathbb{F}_{q}。我们证明:对于任意Fq\mathbb{F}_{q}-对称无记忆信道、任意码长与任意码维数,此类极化码中的所有码字符号在连续消除(SC)译码器下具有相同的符号错误率(SER)。

We extend the results in the previous version to polar codes over finite fields. Previously, we only proved the results for binary polar codes
