广义门限的软判决最小距离译码

Soft Decision Minimum Distance Decoding Using General Threshold

本文讨论了最小距离译码的各种等价形式及相应的广义门限,提出了广义门限的软判决最小距离译码。该方法的优点在于保持译码性能不变或性能损失较小的前提下,大大加快了译码的平均速度。

This paper discusses several equivalent forms of minimum distance decodings and Several gene-ral threshold and proposes the minimum distance decoding with the general threshold. The advantage of the decoding given by this paper is fast mean decoding speed while the loss of its performance is much small.
