【摘要】 根据多基站协作系统的特点,提出了2种次优的低复杂度天线选择算法:基于协作基站总体信道矩阵范数的天线选择算法(aggregate channel frobenius norm antenna seltction,ACFAS)和基于每个协作基站信道矩阵范数的天线选择算法(individual channel frobenius normantenna seltction,ICFAS)。ACFAS算法以全部协作基站与用户的整体信道矩阵的Frobenius范数为天线选择的目标函数,而ICFAS算法则以参与协作的每个基站与用户的信道矩阵的Frobenius范数为天线选择的目标函数。仿真结果和复杂度分析表明,提出的多基站协作系统天线选择算法复杂度较低,但是系统的容量性能受到损失,是一种次优的低复杂度天线选择算法。更多还原

【Abstract】 Two kinds of antenna selection algorithm one proposed according to the characteristics of base-station coordination system.One is called aggregate channel frobenius norm antenna selection(ACFAS),another one is individual channel frobenius norm antenna selection(ICFAS).The object function of antenna selection in ACFAS is based on the aggregate channel frobenius norm of all of the coordinating base-stations and users,while the object function of ICFAS is based on the individual channel frobenius norm of every base-station and user.With the complexity analysis and system simulations,it is proved that the antenna selection algorithms proposed are capable of reducing the complexity,yet at a cost of system capacity lost.So they are suboptimal algorithms.更多还原
