基于四电平脉冲幅度调制（PAM-4）符号转换，研究了一种二维（2D）符号映射技术，通过评估传输数据质量自适应地设置均衡器参数。2D符号转换映射使得能够可视化符号间干扰（ISI）的程度。仿真结果表明，该二维符号映射方法可以有效地评估码间干扰对PAM-4数据传输质量的影响，并能直观地反映均衡效果。讨论了二维映射的应用以及二维映射向三维映射的扩展。
Based on four-level pulse-amplitude modulation (PAM-4) symbol transition, this study investigated a two-dimensional (2D) symbol mapping technique that evaluates the quality of transmission data to set equalizer parameters adaptively. The 2D symbol transition mapping enables visualization of the degree of intersymbol interference (ISI). The simulation results demonstrate that the 2D symbol mapping can evaluate the PAM-4 data transmission quality degraded by ISI and can visualize the effect of equalization. The applications of 2D mapping and the extension of 2D mapping to 3D mapping are also discussed.
