本文以LTE系统的小区间干扰协调为研究背景,对频域资源进行合理规划、分配,提出了一种基于优先级的干扰协调方案。改善了小区边缘用户服务质量。仿真结果表明,本文提出的基于优先级的干扰协调方案,大大提高了用户的信噪比,使用户的吞吐量稳定在相对高度,块误码率保持相对较低值,在提升了系统的整体性能的同时也极大的提升了小区边缘用户的性能。在4G网络的大背景下,本文提出的方案对4G网络的规划有一定的应用价值。
In this dissertation, taking the inter-cell interference coordination of LTE system as the research background, this paper puts forward a priority-based interference coordination scheme by reasonably planning and allocating the resources in the frequency domain. Improve the service quality of cell edge users. The simulation results show that the priority-based interference coordination scheme proposed in this paper greatly improves the signal-to-noise ratio of the users, keeps the user throughput stable at a relatively high level, and keeps the block error rate relatively low, which improves the overall system Performance at the same time also greatly enhance the cell edge of the user’s performance. Under the 4G network background, the scheme proposed in this paper has certain application value for the planning of 4G network.
