摘要
针对传统研究中多状态信道模型划分无相应理论依据的情况,分析了移动通信信道传播特性,阐述几种单一状态下经典的移动通信信道统计模型并推导它们的二阶统计特性,再结合移动通信的传播特性,提出了基于模糊数学的移动通信信道划分方法,建立符合实际信道特性的多状态移动信道Markov模型,最后通过相关数学理论推导和仿真验证了基于模糊数学的多状态Markov模型更加贴近实际信道特性.
According to the situation that there is no corresponding theory for the division of multi-state channel model in the traditional research,the propagation characteristics of mobile communication channels are analyzed.Several classical statistical models of mobile communication channels are illustrated and their second-order statistical properties are derived.Based on the propagation characteristics of mobile communication,a mobile communication channel partition method based on fuzzy mathematics is proposed,and a Markov model of multi-state mobile channel conforming to the actual channel characteristics is established.Finally,it is proved that this multi-state Markov model based on fuzzy mathematics through the derivation and simulation of the related mathematical theory is closer to the actual channel characteristics.
