| Abstract: | Interference optimization is the key to improve the quality of wireless network. At present, there are mainly Intra-system and Inter-system interference in uplink and downlink of TD-LTE system, and the mix of several interference types makes it much more difficult to control interference power. Based on the study of interference theory, this paper proposes a TD-LTE interference processing method and introduction an interference diagnosis system, which can effectively reduce the interference power of TD-LTE network and improve user''s perception. |
