该文以简单分群的Markov模型作为移动信道的模型,给出并分析了一组不同调制方式、不同传信率下的移动信道的Markov模型的实例。分析的结果与实测值吻合得很好,证明简单分群的Markov模型具有简单、准确的特点,为研究移动信道的可靠性提供了方便。同时,进一步提出了自适应Markov模型的概念和建立方法,使模型可适应不同信道下的不同信噪比,更加实用化。
In this paper, Markov model with simple grouping is taken as the model of mobile channel. An example of Markov model of mobile channel with different modulation schemes and different transmission rates is given and analyzed. The results of the analysis are in good agreement with the measured ones. It proves that the Markov model with simple clustering has the characteristics of simplicity and accuracy, which is convenient for studying the reliability of mobile channel. At the same time, the conception and the establishment of adaptive Markov model are further proposed. The model can adapt to different signal-noise ratios under different channels and become more practical.
