用于智能天线技术中的MMSE波束成形器

近年来,智能天线正受到越来越多的重视,他可以有效地提高移动通信系统的容量,改善系统的信噪比。智能天线的自适应波束成形中,有多种不同的自适应波速成形算法,在这里重点讨论使用MMSE算法的波束成形器,因为使用MMSE接收机在静态(或者恒参)信道中,MMSE接收机的性能比较好。在简单介绍智能天线技术之后,通过对MMSE算法和MV算法,设定条件进行仿真对比,来阐述MMSE算法的优势和选择他的场合。

MMSE Adaptive Beamformer for Smart Antenna Skill

Smart antenna has been paid more attention to these years because of its great performance.It can increase the capacity of the mobile communicational system efficiently and improve the signal-noise-ration of the system.There are so many kinds of beamformers in the smart antenna skills.The beamformer with MMSE arithmetic is emphasized on here,because of the good capacity in static channel.This paper introduces the smart antenna skill in the paper at first,and then,expounds the predominance of MMSE and the environment in which we use it by comparison between MMSE and MV after setting some factors for simulating.
