| 摘 要： | 提出了一种新的Markov两状态信道模型,即理想信道状态和非理想信道状态。此模型对于理想信道状态,总的接收信号能量服从莱斯概率密度分布;对于非理想信道状态,接收信号能量服从Corazza模型的概率分布。结果给出了仿真和测量的累积分布、电平交叉率和平均衰落持续时间的比较图,这些图表明,此假设不仅简单、准确,而且具有一定的实际意义。

| Abstract: | A novel two-state Markov channel model is proposed,which assumes that the envelope of the received signal subjects to Riciean distribution for an ideal channel state while the envelope of the received signal Corazza s channel model for a non-ideal channel state.The comparative results of the cumulative distribution,the level-crossing rate as well as the average duration of fades of simulation and measurement show that the assumption is simple,reasonable and useful in practice. |
