摘要: 将认知无线电运用到异构网络的干扰管理中,分析了基于信道复用的认知干扰管理策略和基于机会选择的认知干扰管理策略,并对两种干扰管理策略进行了比较。结果表明,基于信道复用的认知干扰管理策略适合于宏小区用户,基于机会选择的认知干扰管理策略适合于家庭用户。使用了认知干扰管理策略后,用户的性能得到较大的提升,即使宏小区中的家庭基站较多时,用户SINR的中断概率依然很小。

Abstract: Cognitive radio can be applied to interference management in heterogeneous network. An analysis and comparison of interference management schemes based on channel reuse and opportunistic selection are made. It proves that interference management scheme based on channel reuse is more suitable for macrocell user and the other fits for fem-tocell user better. Besides, the two interference management schemes both improve the system performance greatly even if femtocells are largely deployed in a macrocell.
