摘要 在多用户MIMO下行系统应用中,在保证MIMO复用增益的情况下采用合适的用户调度算法保障用户的公平性一直是问题的关键.通过研究发现比例公平算法严格保障了用户的公平性,但用户公平性是通过单用户调度的方式实现的,这对系统容量有较大影响.提出一种基于用户集调度的比例公平算法,牺牲了一定的公平性以换取系统容量的提升.本文在基于块对角算法的MIMO系统上,对提出的算法进行了仿真验证.仿真表明,在用户集数目适当的条件下,所提出的算法将能在系统复用增益下降不大的前提下保证用户的近似公平. Multiple user(MU) MIMO Downlink techniques are capable of achieving a multiple access capacity gain by simultaneously supporting multiple users.MU scheduling scheme should be properly designed,which may ensure the multiple access capacity gain and the fairness as well.Against this background,we propose a improved Proportion Fairness(PF) algorithm,which intend to solve the tradeoff problem between the multiplexing gain and fairness.Simulation results show that the proposed algorithm can get the multiplexing gain while ensuring the fairness.
