| 摘 要： | 提出了一个建立在简单分群的 Markov 模型基础上表示移动信道的三状态Markov 模型,利用非线性最小二乘拟合法求得了此模型的解析表达式,并计算出描述模型的概率转移矩降 P。根据此模型给出的参数,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信道差错序列{e_(?)}。模拟结果表明,用三状态 Markov 模型表示移动信道比用 GEC 模型表示移动信道具有更高的精度,而且比一般分群的 Markov 模型更简单、实用。

| Abstract: | In this paper,a simple partitioned Markov model with three states for mobile radio channel is presented based on a field test curve. The expression of this model and its transition probability mattix P are obtaitied by the eurve fitting with the ntethod of nonlinear least square. In terms of the parameters from this model,burst error sequence is ge- nerated by Software on a computer.The simulation results show that the simple partitioned Markov model with three states is more close to the real channel than GEC model and it is more simple and more pra- ctical than the general partitioned Markov model. |
