随机解码是迭代地解码诸如低密度奇偶校验码的纠错码的方法。由于其解码算法的计算简单性，随机解码不仅提供了低硅面积，但也有竞争力的性能。在本文中，我们研究了不同的技术来确定随机解码器在最终决策过程中产生的码位。我们研究了一种有效的方法，其中根据输出节点生成的最终随机比特直接决定码比特。这种观察有助于节省芯片面积，并提供高吞吐量的随机解码器。
Stochastic decoding is a method to iteratively decode error-correcting codes such as low-density parity-check codes. Due to the computational simplicity of its decoding algorithm, stochastic decoding provides not only low silicon area but also competitive performance. In this paper, we research the different techniques used to determine the code bits generated by stochastic decoders during the final decision process. We investigate an efficient method where code bits are directly decided based on the final stochastic bits generated at output nodes. This observation contributes to saving chip area and providing high throughput for stochastic decoders.
