摘要
针对一个复杂高速信令通道的有损问题,提出以最大失真分析的算法评估信道。通过对脉冲响应的叠加法,求取高速信号系统最坏眼图及最坏码型。最大失真分析算法是分析信号链抖动和噪声特征的有效工具。仿真结果验证了该算法的有效性,实现了快速、高效、准确地求出系统最坏情况下的眼图和码型。
In view of the complex high speed signaling channel loss problem, this paper puts forward the PDA (Peak Distortion Analysis) algorithm to evaluate the channel. The impulse response of the superposition method is used to obtain the worst eye diagram and the worst pattern of the high speed signal system. The PDA algorithm is a powerful tool for the analysis of jitters and noise characteristics of the signal chain. Simulation results show the effec- tiveness of the algorithm which achieves fast, efficient and accurate calculation of the worst-case eye diagram and pattern of the system.
