摘要:
 宏蜂窝与家庭基站的双层组网方案能够有效提高通信系统的容量,解决数据业务拥堵的现状。但是,宏蜂窝基站和家庭基站之间的多种干扰问题严重损害了通信质量,降低系统性能。针对该问题,文中提出了一种分层调度资源—联合抑制干扰的算法。首先构建了内外层系统模型(I-O模型),并对双层交叉混合干扰进行了分析,然后分别在内层和外层提出了时频域资源调度和基于子信道和功率的资源分配算法,最后在系统平台上进行仿真。结果表明,所提算法在小区边缘用户频谱效率、系统用户平均吞吐量等方面达到了良好的效果。
Abstract:
 The coexistence of macro cells and low-power cells forming the heterogeneous double-tiered networks,can effectively improve the capacity of communications systems,solving the situation of data business congestion. However,the interferences between the macro cells and Femto cells severely degrade the quality of communications and prevent the system quality enhanced. Aiming at this problem, propose a hierarchical scheduling resource-joint interference suppression algorithm. First,build a model of the inner and outer layer of the system ( I-O model) ,and analyze the double-cross hybrid interference. Then,put forward an algorithm of resource allocation of time-frequency domain resource scheduling and based on joint subcarrier and power in inner and outer layer. Finally,simulate them on the sys-tem platform. The results show that the algorithm proposed achieves good effects in the spectrum efficiency of the system,the average user throughput and other aspects.
