摘　　要：在无线用户增多,而无线通信小区不能再微小化的情况下,基于分布式MIMO系统,利用群切换思想,提出了智能小区方案,研究了智能小区的重组与切换过程以及功率控制下的无线接入与信道分配策略.仿真表明智能小区有较高的通信速率,可以服务更多用户,更适用于密集用户的无线通信.When the number of wireless user is increasing and wireless communication district can not be more partitioned, distributed MIMO system-based an intelligent cell is proposed by using the tactics of group handover. Recombining and handover of intelligent cell, wireless access and channel allocation are investigated. The simulation results show that intelligent cell can serve more users with an upper communication speed, which is propitious to wireless communication for dense consumer district.
