| 摘 要： | 实际无线通信环境中发送天线之间以及接收天线之间存在相关性.针对以上特点,从多径MIMO信道的特性出发,首先建立发射天线相关系数矩阵和接收天线相关系数矩阵,并将它们引入无线信道的莱斯MIMO信道模型中.最后通过分析LOS MIMO信道相关模型和瑞利衰落MIMO信道相关模型,给出了具体的建模步骤.仿真结果表明采用本文方法产生的信道模型的MIMO系统误码率更低,从而验证了该信道模型能够较好地模拟MIMO系统的空间信道.

| Abstract: | The transmitter antennas or receiver antennas are correlated in the
practical wireless telecommunication environment. According to the above feature
,the correlation coefficient matrixes of transmitter antennas and receiver ante
nnas are first constructed based on the characters of multi-path MIMO channel. A
nd the matrixes are taken into the Rice MIMO channel model. Finally, the detaile
d steps
of constructing channel model are presented through analysing the LOS and Raylei
gh MIMO channel correlation mode.Simulation results show th
at the bit error rate of MIMO system adopting the channel model proposed i
n this paper is lower and the effectiveness of the proposed channel model is pro
ved. |
