毫微微小区系统中的干扰分析与节能技术利用

Interference Analysis and Energy Saving Technologies in Femtocell System

毫微微小区(Femtocell)基站外观与Wi-Fi接入设备相似,发射功率小,适用于家庭及办公室环境。在分析Femtocell系统的资源复用模型和接入过程的基础上,文章针对宏小区(Macrocell)和Femtocell混合网络的干扰问题,通过对随机到达的用户合理分配时频资源,提出一种功率控制方案。该方案能达到系统节能、降低干扰和提高系统性能的目的。

Femtocell is similar to Wi-Fi access devices in appearance and low transmission power. It can therefore be applied in family and office environments. In this paper, wireless resource models and access processes are considered, and a power control scheme is proposed. Time-frequency resources can be reasonably allocated to users who are randomly arrived in order to solve the problem of inteference in macrocell and Femtocell hybrid networks. This scheme can save energy, reduce inteference, and improve system performance.
