| 摘 要： | 协作分集是一种新兴的空间分集技术，能够有效地提高分集增益．而单载波频域均衡技术（SC-FDE）是一种有效对抗多径信道频率选择性衰落的关键技术．文中将这2种技术有机地结合起来，利用改进的空时编码方案并考虑到功率分配对系统性能的重要影响，提出了一种基于DF协议下的功率分配优化算法．并分别采用BPSK、QPSK和16QAM3种调制方式进行比较．仿真结果表明：在3种调制方式下与传统的等功率分配算法相比，新的功率优化算法的SER性能都有显著的提高．

| Abstract: | Cooperative diversity is a new type of spatial diversity technology that can effectively improve the diversity gain.And single carrier frequency domain equilibrium technology(SC-FDE) is a kind of effective key technology that resists multi-path channel frequency selective decline.This paper effectively combines the above two technologies and uses improved space-time coding scheme,considering the influence of power allocation on system performance.A power allocation optimization algorithm is proposed based o... |
