Multiple input/multiple output (MIMO) is a hot topic in wireless communication and has a great advantage in its capacity. We investigate the influence of antenna topology on MIMO capacity and by comparing three topology schemes we find that selecting a proper antenna topology increases the capacity evidently. Three schemes under study are the traditional point-to-point concentrated antenna topology (CON), the multipoint-to-point distributed antenna topology (DIS) and the clustered antenna topology (CLUSTER). We explore their average capacity under different antenna number and power allocation methods. Simulation results show that DIS and CLUSTER excel the traditional concentrated MIMO structure in capacity.
