Abstract (in Japanese) (See Japanese page) 
(in English) In wireless communications, a distributed antenna system (DAS) is a promising technique to increase the spectral efficiency. DAS consists of geographically distributed base station antennas, which enables to perform virtual MIMO transmission and achieve macro-diversity efficiency. DAS has many degrees of freedom such as antenna selection, clustering of antennas, and transmission schemes, and therefore it is complicated to analyze. In this paper, the cluster size in DAS is considered to be similar to the radius of cells in cellular systems. In clustering based on location, the coverage area of clusters and the area of base station antennas used for transmission can be set individually. The simulation results show that the optimal cluster size for base station antennas depends on the scheduling algorithm when analyzed in perspective of area spectral efficiency.
