论文摘要
我们考虑从$ 2 \ times 2 $内核$ \ begin {bmatrix}构建的极地代码 1&0 \\ α&1 \ end {bmatrix} $上的有限字段$ \ mathbb {f} _ {q} $,其中$ q = p^s $是素数$ p $的力量,而$α$满足$ \ \ m mathbb {f} _ {f} _ {p} _ {p}(α(α)$}我们证明,对于任何$ \ mathbb {f} _ {q} $ - 对称内存的通道,任何代码长度和任何代码维度,此类极性代码中的所有代码字符号在连续取消(SC)解码器下都具有相同的符号错误率(SER)。
We consider polar codes constructed from the $2\times 2$ kernel $\begin{bmatrix} 1 & 0 \\ α& 1 \end{bmatrix}$ over a finite field $\mathbb{F}_{q}$, where $q=p^s$ is a power of a prime number $p$, and $α$ satisfies that $\mathbb{F}_{p}(α) = \mathbb{F}_{q}$. We prove that for any $\mathbb{F}_{q}$-symmetric memoryless channel, any code length, and any code dimension, all the codeword symbols in such polar codes have the same symbol error rate (SER) under the successive cancellation (SC) decoder.
