A Comparison of Interference Management Schemes in Cognitive Heterogeneous Network
Qian Ge, Rongfang Song · 2013
Cognitive radio can be applied to interference management in heterogeneous network. An analysis and com- parison 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 femtocell user better. Besides, the two interference management schemes both improve the system performance greatly even if femtocells are largely deployed in a macrocell.
