MIMO系统中天线选择算法研究
ntenna Selection Algorithm of MIMO System
在瑞利衰落信道条件下,通过天线选择可以提高多输入多输出(MIMO)系统的容量,并能有效地降低M IMO系统的复杂度和射频成本,天线选择算法也成为问题的关键。对天线选择算法进行了研究,通过连续选择使MIMO系统容量增加最大的天线的方法,用矩阵及行列式运算导出了一种新的基于贪心思想的天线选择算法,并通过仿真和分析与其它算法进行了比较。
Antenna selection techniques not only can increase capacity of multip le inputmultip le output (MIMO) systems, but also can reduce their comp lexity and cost of RF ( radio frequency) chains in Rayleigh fadingchannels. Hence antenna selection algorithms play an important role in MIMO systems. In this paper, antenna selection algorithms in MIMO systems have been studied and a novel algorithm is p roposed. The novel algorithm is based on Greedy thinking. Through simulation and analysis and other algorithms are compared.
