Wireless communications are susceptible to eavesdropping. To interfere the eavesdropper having multiple antennas, secret information signals and interference signals that are transmitted from multiple antennas are designed. It is shown that our design can be cast into a semidefinite program, which can be numerically solved efficiently. Simulation results are provided to demonstrate the efficiency of the proposed design.
