Abstract

Recent works introduced models based on chaos equations, aiming to simulate transmission processes over mobile radio digital channels at the level of the post detection error time series, and to reproduce their non renewal behaviors. Bursts and clusters of errors are generated by these models exploiting the correlation between successive points sampled from the trajectories of suitable strange attractors. In this paper, automatic search procedures are introduced to optimize the model parameters in order to closely comply with the statistical characteristics of target error sequences derived from DECT system simulators, and some significant results are provided.

移动无线电信道混沌方程模型参数建模实验
最近的研究引入了基于混沌方程的模型,旨在模拟移动无线电数字信道在检测后误差时间序列水平上的传输过程,并再现其不更新行为。这些模型利用从合适的奇异吸引子轨迹中采样的连续点之间的相关性,产生了错误的爆发和簇。本文引入自动搜索程序对模型参数进行优化,使其与DECT系统模拟器得到的目标误差序列的统计特性保持一致,并取得了一些有意义的结果。
