首先，给出了干扰协调的软频率复用原理。
First of all, the article introduces the Soft Frequency Reuse (SFR) principle of interference coordination.
通过仿真，分析并证实了静态软频率复用技术可对边缘用户吞吐量带来极大提升，同时给出并验证了系统中改进型比例公平调度器的最佳配置参数。
On this basis, the scheme of SFR based on power-reuse using modified proportional fair algorithm is studied to prove that SFR can greatly improve cell-edge users' throughput.
