卷积极化码的距离性质

On Distance Properties of Convolutional Polar Codes

Ruslan Morozov, Peter Trifonov

摘要:

提供了卷积极化码的最小距离的下界。由极化矩阵的底行生成的码的广义陪集的最小权得到界。此外,提出了一种卷积极化子码的构造,其在连续消除列表解码下提供改进的性能。对于足够大的列表大小,与具有相同性能的Arikan极化子码相比,卷积极化子码的解码复杂度似乎更低。卷积极化子码的逐次消去列表译码的错误概率低于具有相同列表大小的Arikan极化子码。

英文摘要:

A lower bound on minimum distance of convolutional polar codes is provided. The bound is obtained from the minimum weight of generalized cosets of the codes generated by bottom rows of the polarizing matrix. Moreover, a construction of convolutional polar subcodes is proposed, which provides improved performance under successive cancellation list decoding. For sufficiently large list size, the decoding complexity of convolutional polar subcodes appears to be lower compared to Arikan polar subcodes with the same performance. The error probability of successive cancellation list decoding of convolutional polar subcodes is lower than that of Arikan polar subcodes with the same list size.
