【摘要】 相比传统的宏蜂窝网络,分层异构网络是实现系统容量增强的一种很有前景的技术。尽管如此,由于家庭基站与宏基站同频部署,且它们被随机部署,异构网络中的干扰可能会更强。为了提升网络吞吐量,研究了一种新型的基于进化博弈的小区附着算法,为最小化小区间干扰,提高网络吞吐量提供了理论参考。更多还原

【Abstract】 The heterogeneous network( Het Net) technology is a promising method for achieving significant gain in capacity compared to conventional single-tier macro-cellular networks. Nevertheless,Het Nets may potentially result in much higher interference because femtocells operate on the same channel as the macro-cellular network,and Het Nets are unplanned deployment. In order to enhancing the system throughput,an innovative cell association algorithm is investigated by introducing evolutionary game model in Het Nets. The proposed scheme provides theoretical reference for restraining interference and improving system throughput.更多还原
