Information-Theoretic Capacity Analysis in Triangle Cellular Communication System

In the distributed antenna systems (DAS), if it is assumed that there is no power cooperation among the distributed antenna modules, namely, with the per-antenna constraints, the antenna module can cover less area than that with the total power constraints only. In this paper, a triangle cellular communication system (TCCS) and its power control scheme are proposed. Then, we investigate the information-theoretic capacity of TCCS based on the single-user assumption and multi-cell environment. Through simulation, we find that TCCS has a smooth capacity distribution in deferent parts of the cell. The numerical results show that TCCS can enlarge its covering area with the per-antenna constraints. Furthermore, TCCS with its power control scheme gets a capacity as about 2 times high as that with the traditional power control scheme.
