This paper studies a cooperative cognitive radio net-work 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. It involves three basic elements: first,
how to split the power for relaying the primary signals and fo
