On the Asymptotic Performance of Iterative Decoders for Product Codes

Moshe Schwartz, Paul H. Siegel, Alexander Vardy

摘要:

我们认为硬判决迭代解码器的产品代码在擦除通道,它采用重复轮的解码行和列交替。我们推导出精确的渐近概率解码失败的纠错能力的行和列的代码,解码轮数,和信道擦除概率的函数。我们研究的情况下,能够纠正一个恒定的错误量的代码,和代码的情况下,能够纠正一个恒定的分数,他们的长度。

英文摘要:

We consider hard-decision iterative decoders for product codes over the erasure channel, which employ repeated rounds of decoding rows and columns alternatingly. We derive the exact asymptotic probability of decoding failure as a function of the error-correction capabilities of the row and column codes, the number of decoding rounds, and the channel erasure probability. We examine both the case of codes capable of correcting a constant amount of errors, and the case of codes capable of correcting a constant fraction of their length.
