摘　　要：世界各国频谱资源较为紧张,由于无线通信信道质量具有时域的随机性,其受信号衰落、电磁干扰、空间路径耗损等因素影响较大,不利于信号的传输,从而造成频谱资源的巨大浪费。介绍了自适应功率分配相关技术,分析了多时变衰落信道〔Gilbert Elliot信道〕状态进行马尔可夫决策过程(MDP)抽象为数学模型,研究通信信道功率分配决策过程。提出信道置信度假设的功率自适应分配方案。Due to the randomness of wireless communication channel quality in time domain, it is greatly affected by signal fading, electromagnetic interference, space path loss and other factors, which is not conducive to the transmission of signals, resulting in a huge waste of spectrum resources. This paper introduces the adaptive power allocation technology, analyzes the markov decision process (MDP) of multi-time-varying fading channel (Gilbert Elliot channel), abstracted it into mathematical model, and studies the power allocation decision process of communication channel. An adaptive power allocation scheme based on channel confidence assumption is proposed.
