标题： Iterative decoding of Generalized Parallel Concatenated Block codes using cyclic permutations

摘要： 迭代解码技术由于其性能以及在大多数通信系统中的应用而变得流行。 在本文中，我们提出了一种新的应用，将我们的迭代解码器应用于GPCB（广义并行级联块码），该码使用循环排列。 我们引入了组件解码器的一个新变体。 经过大量仿真；与几种现有方法相比，得到的结果非常有前景。 我们评估了各种参数对组件码、交织器大小、块大小和迭代次数的影响。 得到了三个有趣的结果；第一个结果是，新组件解码器在比特错误率（BER）方面的性能与原始解码器相对相似。 其次，我们的Turbo解码在某些线性块码上优于另一种Turbo解码器。 第三，提出的GPCB-BCH（75, 51）的迭代解码距离其香农极限约2.1dB。 显示英文摘要

摘要： Iterative decoding techniques have gain popularity due to their performance and their application in most communications systems. In this paper, we present a new application of our iterative decoder on the GPCB (Generalized Parallel Concatenated Block codes) which uses cyclic permutations. We introduce a new variant of the component decoder. After extensive simulation; the obtained result is very promising compared with several existing methods. We evaluate the effects of various parameters component codes, interleaver size, block size, and the number of iterations. Three interesting results are obtained; the first one is that the performances in terms of BER (Bit Error Rate) of the new constituent decoder are relatively similar to that of original one. Secondly our turbo decoding outperforms another turbo decoder for some linear block codes. Thirdly the proposed iterative decoding of GPCB-BCH (75, 51) is about 2.1dB from its Shannon limit.
