| 摘 要： | 在异构网络组网形式下,为了降低小区间干扰对边缘用户的影响,提高系统容量,对基站进行分簇研究。在多用户下的情况,以最大化边缘用户的和速率为目标,通过设置路径损耗门限来选择为用户进行协作通信的基站。分析对比了不同分簇方式下的用户平均速率情况,并且通过观察不同的门限值对应的速率变化情况,合理的选择门限值。仿真结果表明,该方法在一定程度上能够有效提高数据传输速率,当信噪比为18 d B时,路径损耗门限法在系统的平均传输速率方面较阈值法提升了1.02 bit/s,即用户的平均数据速率获得了17%的提升。

| Abstract: | In order to reduce the interference of the inter cell interference and improve the system capacity, the base station is studied in the form of heterogeneous network. In the case of multiple users, to maximize the sum of the edge user''s rate, through setting the path loss threshold to select the base station for collaborative communication. The average rate of users in different clustering methods is analyzed and compared, and the reasonable threshold value is selected by observing the rate variation of different threshold values. The simulation results show that the clustering method has certain advantages in improving the transmission rate of the system compared with the previous power maximum method and threshold method. |
