But many papers are only focused on these cases and do not consider multiuser diversity. A minimal capacity loss Round-Robin scheduling algorithm is presented in this paper. Coupled with this algorithm,the multiuser diversity is studied in downlink distributed antenna system based on zero-forcing beamforming. The results show that with the same antenna number and sum power Distributed Antenna System(DAS) is preferable to Co-located Antenna System(CAS) in term of multiuser diversity gain. The minimal capacity loss Round-Robin scheduling algorithm distinctly outperforms common Round-Robin scheduling algorithm and it can be used in DAS and CAS. %K Mobile communication %K Distributed Antenna System(DAS) %K Multiuser diversity %K Channel capacity %K Round-Robin(RR) scheduling
