用于失活译码的LT码设计

LT Code Design for Inactivation Decoding

Francisco Lázaro Blasco, Gianluigi Liva, Gerhard Bauch

摘要:

我们提出了一个简单的LT码失活解码模型,可以用来估计作为LT码度分布的函数的解码复杂度。该模型被证明是准确的,在各种设置的实际意义。所提出的方法允许进行数值优化的LT码的度分布,旨在最大限度地减少解码所需的失活的数量。

英文摘要:

We present a simple model of inactivation decoding for LT codes which can be used to estimate the decoding complexity as a function of the LT code degree distribution. The model is shown to be accurate in variety of settings of practical importance. The proposed method allows to perform a numerical optimization on the degree distribution of a LT code aiming at minimizing the number of inactivations required for decoding.
