- Abstract
In this paper, by adopting a research method integrating interference neutralization, interference alignment and cognition network, the degrees of freedom of IC coexistence composed of two single-antenna users in the master network and subnetwork is studied. The inner bound and outer bound of the system under every cognition condition are researched. According to the research result, the maximum degree of freedom in the inner bound is 4, the same as the outer bound value. Therefore, it is concluded that with the increase of cognition messages, the inner bound of degrees of freedom becomes closer to its outer bound. Also, the degrees of freedom region of the special cognition shown in Case14 is analyzed.
