摘要
分析了多用户特征模式传输(MET)的结构并研究了一种低复杂度的调度算法,同时研究了一种自适应比例公平调度算法.在基站端采用多用户特征模式传输来消除用户间干扰,增加系统吞吐量,同时在保证用户传输速率的情况下使用比例公平调度和自适应比例公平调度算法提高系统的公平性,在同一时刻选择最优用户集进行传输.仿真与分析表明:多用户信道特征模式传输与自适应比例公平算法相结合不仅保证了系统速率,还提高了系统的公平性.
The structure of multiuser eigenmode transmission(MET) was studied by low-complexity implementation,and a adaptive scheduling scheme was proposed.The base station used MET to eliminate the users′ interference and increases the system capacity.The adaptive proportional fair scheduling algorithm was used to ensure the system′s fairness.The best user for transmission was closed at the same time.The simulation results show that the combination of MET and the proportional fair scheduling scheme not only ensure the system's rate,but also improve the system′s fairness.
