【摘要】 针对采用随机波束成形的MIMO下行链路,提出了一种多用户调度算法。在接收端利用每个用户在各个波束方向上的比例公平性参数来得到容量门限。仿真结果显示,这种调度算法相比其他门限调度算法,在系统性能无明显损失的情况下,有效地减小了反馈量。更多还原

【Abstract】 A multi-user scheduling method for MIMO downlink system using random beamforming technique is proposed.At receiver,the capacity threshold is obtained by using proportional fair parameter in each sub-channel on each user.The simulation shows that,compared with other methods,this method can reduce feedback greatly without much losing in system performance.更多还原
