| 摘 要： | 本文提出一种联合考虑空间分集与Doppler分集方法来提高时变多径衰落信道下高速移动通信系统的性能。给出了联合空间分集与Doppler分集的多天线发送多天线接收(MIMO)系统模型,推导出了时变衰落信道下系统所能获得的最大分集阶为ML(Q+1),并提出了实现该分集增益的编码方法。研究了系统的中断性能,并通过仿真验证了2种分集技术的结合可以带来系统性能的提高。

| Abstract: | Jointing space diversity with Doppler diversity in MIMO(multiple input multiple output) wireless communications is researched in this paper. The MIMO channel model that joints space diversity with Doppler diversity is set up. Based on it, we show that the maximum diversity order is ML(Q+1). Then, the coding scheme in this situation is proposed. Following this, outage capacity is researched, and simulations are provided to corroborate our theoretical findings. |
