| Outline of Final Research Achievements |
If a base station of a wireless communication system has multiple transmit antennas, it is possible to control the direction of its transmitted signal by using beamforming. On the other hand, if the receiver has multiple receive antennas, it is possible to enhance the received signal by using beamforming.
We consider a wireless LAN, where the base station utilizes beamforming to combat colluding eavesdroppers with multiple antennas and transmitting artificial noises. The beamformer and the artificial noises are optimally designed to achieve the prescribed signal to interference and noise ratio (SINR) at the legitimate receiver and the maximum allowable SINR at the eavesdroppers.
