| 摘 要： | 为了能够以较小的实现复杂度有效减少多天线蜂窝系统中的小区间干扰,同时保证系统中的用户公平性,提出一种新的多小区联合调度算法,提出的算法的复杂度远远低于最优多小区联合调度算法。该算法将系统分簇并在每个簇内按一定比例选择部分平均速率较低的用户,之后在簇内按照给定的优化目标进行联合调度。仿真结果表明：与单小区调度算法相比,提出的多小区联合调度算法可以显著增加系统平均速率,而且可以取得与单小区调度算法类似的用户公平性。

| Abstract: | A novel multicell joint scheduling algorithm with low complexity is proposed to effectively reduce inter-cell interference in multiple antenna cellular systems while guarantee the user fairness.The implementation complexity of the proposed algorithm is much lower than that of the optimal multicell joint scheduling.In the proposed algorithm,the system is divided into clusters,and the users with low average rate are selected in given proportion in each cluster.And joint scheduling is then performed to optimiz... |
