Interference alignment based on adaptive eigenmodes in a multiple-input, multiple-output cognitive radio network
This article aims to optimize the information rate of a cognitive radio network with multiple secondary users. A primary user rate optimization approach based on dichotomy of the degree of freedom is proposed, where the primary users’ eigenmodes are adjusted according to its rate requirement. In ord...
