Capacity Analysis of Multi-user Diversity in Generalized Distributed Cellular Architecture

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
