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.
