摘要

为NRZ信号开发的统计方法是否适用于PAM-4调制?不完全是。我们证明了一些基本原理(例如，基于边缘的分析，将抖动PDF转换为垂直噪声)仍然有效，但解决流程应该进行修改。修改包括:PMF累加器的数量，它们的初始化和输入输出连接，权重因子，转移概率，以及它们与高阶相关系数的关系。

Accurate statistical analysis of high-speed links with PAM-4 modulation considering transmit jitter, data-dependent transitions, and correlated input patterns

Do statistical methods developed for NRZ signals work for PAM-4 modulation? Not entirely. We show that some basic principles (e.g., edge-based analysis, conversion of jitter PDF into vertical noise) remain valid, but the solution ﬂow should be modified. Modifications include: the number of PMF accumulators, their initialization and input-output connections, weight factors, transition probabilities, and their relationships to the high-order correlation coefficients.
