分析了在广义分布式蜂窝结构--群小区中采用多用户分集（MUD）策略的性能。该结构可以充分利用多天线技术，解决载波频率增加带来的频繁切换问题。本文分析了群小区的系统容量，重点讨论了群小区多用户检测带来的容量增益。通过理论分析给出了MUD购买的容量增益，并推导出了容量增益的下界。仿真结果验证了理论分析的正确性
This paper analyzes the performance of utilizing multi-user diversity (MUD) strategy in generalized distributed cellular architecture-group cell. The group cell architecture can take full advantage of multi-antenna technologies and solve the problem of frequent handover caused by increase of carrier frequency. The system capacity of group cell is analyzed and the capacity gain brought by MUD in group cell is emphasized in this paper. The theoretical analyses are provided to give the capacity gain bought by MUD and the bottom bound of capacity gain is deduced. Simulation results are also presented to verify the theoretical analyses
