摘要
研究和模拟了建立一个自适应移动信道模型的全过程。根据所建模型的参数,用计算机软件实现方法产生出描述移动信道长突发错误特性的差错序列。并提出了一种门限电平法检验了所建模型的精确度。
An adaptive statistic model for mobile communication channel is studied and simulated. According to the parameters of the model set up, an error sequence describing the long burst error characteristics of the mobile channel environment is generated on computer. A test method using threshold technique is presented to verify the accuracy of the adaptive channel model. The simulation results show that the adaptive Markov model with three states is more accurate and practical than the conventional mobile channel model and is a feasible scheme for optimization of mobile communication channel model.
