In this paper, the authors study much antenna beamforming algorithm research in cognitive radio two-way relay system. In this system, two primary users exchange information by second users, and the second users to configure multiple antennas, a user through the superposition signal sends it to the primary users, therefore in this paper the key problem is how to divide the primary user information of the signal power and power of user information signal; How to design the main users of beamforming matrix; How to design the beam forming matrix of users.
