论文摘要
我们提出了一种概率的塑形方法，用于利率信号传导，其中低率信号使用灵活的分布控制器控制高速数据流的所需概率范围。此外，我们在系统的极性代码中引入了冷冻位索引的运行长度感知值，以最大程度地减少运行长度而不使用运行长度限制代码。与基于混合调制方案的相关工作相比，我们的紧凑型系统可以支持具有出色的光谱效率的软否决前纠正解码。
We propose a probabilistic shaping approach for region-of-interest signaling, where a low-rate signal controls the desired probabilistic ranges of a high-rate data stream using a flexible distribution controller. In addition, we introduce run-length-aware values for frozen bit indices in systematic polar code to minimize the run-length without using run-length-limited code. Our compact system can support soft-decision forward-error-correction decoding with excellent spectral efficiency compared with related work based on hybrid modulation schemes.
