摘　　要：提出了一种应用于虚拟多输入多输出(VMIMO)系统中基于最小均方误差串行干扰消除(MMSE-SIC)接收机的分组可调公平配对调度算法.算法通过比例公平(PF)调度选取首用户,并采用分组与所设计的可调度量准则相结合的方式选择配对用户.仿真结果表明,该算法能够在开发多用户分集增益的同时,利用MMSE-SIC接收机的特点使小区边缘用户的服务质量得到提高.并且通过可调系数获得系统吞吐量与用户公平性之间的平衡.Based on minimum mean square error-successive interference cancel （MMSE-SIC） receiver, a fairness adjustable grouping pairing scheduling algorithm is proposed in virtual multiple input multiple output （VMIMO） systems. This algorithm makes use of the proportional fair （PF） scheduling to select the primary user, and applies grouping as well as adjustable metric criterion designed to select the paring user. The comparison simulation results show that the scheme exploits the multiuser diversity gain, meantime, improves the service quality of the users at the cell edge. Furthermore, the tradeoff between the system throughput and user fairness can be achieved by varying an adjusting coefficient in the algorithm.
