Information-Theoretic Capacity Analysis in Triangle Cellular Communication System
Zhen Wang, Xingzai Lv, Jinkang Zhu · IEEE Vehicular Technology Conference · 2006
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.
