摘　　要：传统动态ICIC方法通过频率协调避免同一资源被调度,实现同频干扰的抑制,但是该方法在负载过高的环境下,不能完成有效抑制。针对描述的情况,融合同频干扰抑制以及数字同频干扰抑制,提出TD-LTE同时同频双工同频干扰电源抑制方法。其硬件包括数字模块、同频模块以及同频干扰重建模块,对各模块的组成结构进行设计。给出了该方法的软件流程过程。实验检测结果表明,所提方法具有较高的同频干扰抑制性能,可增加小区边缘用户的吞吐量,增强频带利用率。Traditional dynamic ICIC method can avoid the scheduling of same resource and restrain the same frequency in- terference, but can＇t realize effective suppression under overload condition. Therefore, a power supply suppression method of TD- LTE same frequency duplex and same frequency interference is presented, in which the suppressions of shared-frequency inter- ference and digital shared-frequency interference are fused. The hardware of the system includes the digital module, same fre- quency module and same frequency interference reconstruction module. The composition structure of each module was designed. The software process of the method is given. Experimental testing results indicate that the method has high same frequency inter- ference suppression performance, can increase the throughput of cell edge user, and enhance the bandwidth utilization.
