| 摘 要： | 针对多输入多输出(MIMO)系统中发射天线之间存在的相关性对系统性能的影响,在已有的基于相关矩阵自适应调整发射功率和相位的预编码算法的基础上,增加基于最小判决距离最大化准则的自适应调制,使接收端能得到均衡且总体最小的误码率.仿真结果表明,该算法可更好地自适应信道,在误码率为10-2时,能取得4dB的增益. |
| 关 键 词： | 多输入多输出 预编码 自适应调制 功率优化 |

| Abstract: | The correlation between transmit antennas of multiple input multiple output(MIMO) system have serious effect on performance of the system.An adaptive modulation based on maximization of the minimum judgment distance was added to the existing pre-coding algorithm based on correlation matrix adaptive transmit power and phase,to achieve a balanced and minimum BER at the receiver.Simulation results indicated that the new scheme could achieve 4 dB gain at a BER of 10-2. |
| Keywords: | MIMO Pre-coding Adaptive modulation Power optimization |
