output decoder meaning in English

输出译码器

For practical implementations , simpler decoding algorithms have been suggested . this decoder implements iterative decoding of tpcs using a soft - input hard - output decoder , followed by reliability calculations to obtain oft - decisions from the hard - output of the decoder . the performance of this decoder is nearly optimal and thus the decoding strategy presents a good compromise
针对实际应用中存在的计算复杂问题，在重复译码实现中采用软进/硬出的简化算法，用可靠度估计从硬判决输出中获得软信息，从而使译码器在性能优越和计算简便之间获得了一个很好的折中，并通过硬件实现了tpc的实时解码，在低信噪比（ eb / n0 ）的条件下取得了非常低的误码率。
