摘要: 分布式通信系统可以抑制干扰，增大容量。为了在现有的系统中引入分布式处理的增益，该文提出了有序分布的正六边形小区通信系统。该系统可兼容现有的定向天线覆盖的蜂窝结构，利用3个相邻基站的共同覆盖形成有序分布的正六边形小区。该文分析了该结构下的共道干扰和中断容量，提出了优化小区容量的设计参数。仿真结果显示，相同条件下，采用中断容量设计的有序分布的正六边形小区通信系统容量相对于采用信噪比准则设计的同类系统及广义分布式天线系统都有显著的增益。Abstract: Distributed wireless communication system can suppress the interference and enlarge the capacity. This paper proposes a novel orderly distributed hexangular cell system to introduce the gain of distributed system into the existing cellular system. It uses 3 adjacent BSs of the existing system to constitute a new cell based on the typical directional antenna configuration. The co-channel interference and outage capacity are analyzed, then a parameter design criterion is proposed. Simulation results show that the new system offers large capacity gain over the same system designed based on signal to noise ration and generalized distributed antenna system.
