基于自适应的去天线相关性方法

Antennas Decorrelation Method based on Adaptive Algorithm

采用多输入多输出(M IM O)技术是军用移动通信发展的必然趋势。然而,实际的M IM O天线之间是相关的,这种相关性会降低M IM O的性能。通过在发射端发送训练序列,采用自适应方法,在接收端可以将M IM O相关系数提取出来。仿真结果表明,分离出的相关系数能够非常接近实际的相关系数。因而,采用这种方法可以比较好的去除天线之间的相关性,可以使M IM O技术有效的应用在军用移动通信中。

Multiple-input multiple-output(MIMO) system will be applied to the military mobile communication in the future.But there exists the correlation among the working antennas in a MIMO system,and the correlation may affect the function of MIMO.Using adaptive algorithm,the receiver can pick up the correlation coefficient after the transmitter transmits the training sequences.The result of simulation shows that the picked-up coefficient is similar to the real coefficient.Therefore,antennas decorrelation method is...
