| 摘 要： | 本文提出了下行多用户多天线系统中一种新的基于Tomlinson-Harashima预编码(THP)的低复杂度调度排序算法.该算法根据THP与误符号率的特点,将调度和排序结合在一起,有效降低了复杂度.仿真结果表明,本文提出的算法在平均误符号率性能上逼近贪婪调度best-first排序,而复杂度更低,在实际系统中有很好的应用价值.

| Abstract: | In this paper,we propose a novel THP scheduling and ordering algorithm with lower complexity in the downlink multiuser multi-antenna systems.This algorithm combines the scheduling and ordering together according to the characteristics of THP and symbol error ratio.Simulation results show that the algorithm can approach the average symbol error ratio performance of greedy scheduling best-first ordering algorithm with much lower complexity.The novel algorithm is promising in the practical systems. |
