摘要/Abstract

摘要： 功率分配是协同通信中的关键技术，为了研究协同通信对系统容量的提升，提出多中继和多接收天线功率分配的协同通信模型，探讨总功率一定的情况下，以系统容量最大化为准则的最优功率分配算法，采用放大转发模式，得出优化的功率分配算法（Optimum Power Allocation，OPA），并在相同假设条件下与平均功率分配算法（Average Power Allocation，APA)进行比较，可以看出在相同条件下OPA比APA的性能好。由最后的仿真分析可以得出系统容量得到了显著提高。

Abstract: Power allocation is a key technology in cooperative communication. In this paper, for improving the channel capacity, a multi-nodes and multi-antenna model is proposed for the cooperative communication. Under the assumption of the total power is constant, the improved OPA(Optimum Power Allocation) algorithm is proposed which taking the maximum system capacity as rule. Compared with APA (Average Power Allocation), theoretical analysis and simulation results show that OPA has better performance than APA.
