MIMO闭环系统的研究与改进

Some Research and Improvement on Closed-Loop System Based on MIMO Channel

首先研究了基于MIMO信道的闭环系统,该系统将带旋转的闭环MIMO与理想功率分配算法——注水算法相结合。并在此系统基础上,加入各种信道编码,进行仿真比较。分析与仿真结果表明,该系统具有较高的频谱利用率和较好的误比特性能。

We firstly research a family of closed-loop system based on MIMO channel, it is an closed-loop MIMO system with ideal power allocation algorithm based on MIMO channel-water-filling algorithm and rotation matrix. And then we apply some space-time codes to this system.By simulation. It is confirmed that the proposed system yields good performances with high spectral efficiency and better bit-error-rote by analysis and simulations.
