Executive Summary

This paper studies a cooperative cognitive radio network where two Primary Users (PUs) exchange information with the help of a Secondary User (SU) that is equipped with multiple antennas and in return, the SU superimposes its own messages along with the primary transmission. The fundamental problem in the considered network is the design of transmission strategies at the secondary node.
