摘 要: | 长期演进(long term evolution,LTE)上行系统级已有几种常用的干扰抑制技术。但均需要相邻小区间的配合,实现起来相对复杂。从链路级的层面上对干扰抑制技术进行研究,提出一种利用导频辅助进行干扰抑制的方法。该方法不需要小区之间的相互配合,并且不用改变接收机的结构。仿真结果证明:该算法在干扰条件下具有优越性,分析了性能提升的原因,并探究了不同算法粒度对算法性能的影响。 |

Abstract: | There are several conventional interference suppression techniques on the system level of long term evolution (LTE) uplink architecture. However, the implementation of them are relatively complex, as they require corporation between adjacent cells. In this paper, interference suppression technique on link level is studied and a pilot-aided interference suppression algorithm is presented. The new method requires neither mutual collaboration between cells, nor the change in structure of the receiver. Simulation results show the superiority of the proposed algorithm in jamming environment. Theoretical analysis on the performance improvement and the impact of different algorithm granularity are also discussed. |
