| 摘 要： | 针对功率分配对于多中继系统的重要性,对混合转发多中继合作系统的功率分配进行了研究,提出了基于等效信噪比最大化的最优功率分配方案。仿真结果表明:合作伙伴的增加对于系统等效信噪比有积极的影响,但不是随着中继数目的增加无限地改善。在多中继混合转发合作系统中,最优的功率分配对于多中继合作系统的性能有很大的改善。

| Abstract: | According to the importance of power distribution to multiple relay system, This paper studies power distribution in multiple relay system and presents optimal power allocation scheme based on the equivalent SNR is maximized. The simulation results show that: the increasing of the number of partners has a positive effect on equivalent SNR, but not improve without limit. The performance of mixed forwarding multi-relay cooperative communication system with optimal power allocation scheme is better than that with equal power allocation scheme. |
