摘　　要：基于传统的LMS算法,提出了一种新的M IMO智能天线自适应波束形成算法,即LMS-M IMO算法.与传统的LMS算法相比,LMS-M IMO算法在发射端和接收端同时采用了智能天线技术.仿真结果表明,LMS-M IMO算法性能明显优于LMS算法,并且随着发射和接收天线阵元数目的增加,其系统性能得到了进一步改善.A novel MIMO algorithm, namely LMS-MIMO algorithm, was presented based on a conventional LMS algorithm in this paper. Compared with conventional LMS algorithm, the LMS-MIMO algorithm not only adopts smart antennas at receiver part but also at transmitter part. Results of simulation analyses reveal that the performance of LMS-MIMO algorithm is much better than the conventional LMS algorithm that only adopts smart antenna at the receiver part. The performance of this system also is been improved with the increasing the number of the array antennas at transmitter and receiver part.
