摘　　要：协同通信系统中的功率分配方案是指在系统总发送功率一定的前提下,如何在参与协同通信的终端之间合理分配功率,以此优化系统性能。本文针对协同通信系统中的现有功率分配方案,给出较为详细的总结与分类,设定目标函数、信道状态信息、有无中心控制节点与中继数目等四种分类原则,并指出,基于统计信道传输特性的分布式功率分配方案较为符合实际通信系统。Based on the supposition that the total transmitted power allocation is constant, the power allocation scheme is to allocate the power between the terminals joined in cooperative communication in order to optimize the system performance. According to the recent power allocation schemes in cooperative communication system, the detailed summary and classification are given in the paper. Four principles are set to classify these schemes, i. e. , cost function, channel state information, having a centralized controller or not, and relay numbers. It is also pointed that the distributed power allocation scheme based on the statistical channel state information is more suitable for the practical systems.
