摘　　要：考虑多个有损Gilbert-Elliott信道的无线通信系统,凭借部分可观测的马尔可夫决策过程建立数学模型,针对信道无线通信功率分配最优化决策进行简要分析。研究结果表明:当信道难以从不良状态恢复到良好状态时,系统将更倾向于信任目前状态较好的信道,系统集中地将功率传输至状态较好的信道;而当信道从不良好运行的状态逐渐恢复至良好运行状态时的概率与系统继续一直保持良好运行状态的概率大致相同时,系统将保守地将功率均匀地分布在所有信道之上。Considering seeral wireless communication systems with lossy Gilbert-Elliott channels, a mathematical model is established based on part of the observable Markovian decision process, and the optimal decision-making of channel wireless communication power allocation is briefly analyzed. The results show that: when the channel is difficult to recover from a bad state to a good state, the system will be more inclined to trust the current channel in a better state, and the system will focus on transmitting power to the better state channel;and when the probability of returning to a good operating state is roughly the same as the probability of the system continuing to maintain a good operating state, the system will conservatively distribute the power evenly on all channels.
